Bumpsy & Shady

Member Since 2017
He keeps getting these open, oozing sores on his skin (it looks like raw meat). It coincided with when we began Lantus (in October) and is still happening. Another sore "opened" up tonight.

He has a little fit licking and scratching the sight. His reaction almost looks like he's being stung by something. Then he tries to run away and hid from it (the pain/discomfort).

Does anyone gave an insight into what might be going on here? I'm thinking it's the Lantus and maybe asking the vet to switch to something else.

...here is a pictures of what I'm talking about.

Anyone else had any experience with this or anything similar? Any advise?

There have been cats that are allergic to Lantus altho not common. It's acid based so may also sting. It didn't bother KT but Dakota cringed when I gave him his shot. I changed to Levemir 3 years ago, shot times are no big deal. I much prefer Levemir anyway. It's still a depot insulin, just works differently. I don't remember seeing one with this much hair loss tho'....

The thing is, is that it's not necessarily happening at the injection site (I think one did, but not so much on the others) which lead me to believe it wasn't the Lantus, but it keeps happening. He has one that's healing up on the other side which was pretty much the same size as the current.

What do you like better about Levemir? If it is still a depot insulin, then why would I expect different results? Because Lantus is acid based? I find that if I let the Lantus warm a little bit it doesn't seem to bother him like a cold shot does. I'm still new to all this so really feel like I'm flying blind.

Thanks! I appreciate you response/input!
 
Since it's not at injection sites, it's likely not Lantus then.

Levemir numbers are more steady rather than a 'smile' curve. It's method of precipitation differs from Lantus, it works better for Dakota. That's the key - the best insulin for anyone's cat is the one that works best for them.

You've got lots of experience in many other sugar cat parents here - ask questions. :) I'm glad letting it warm works good for him!
 
He's not over grooming the spot? Could it be Cushing or a food allergy? My sisters dog got spots like that in the fall. An allergy test revealed he was very allergic to ragweed.
 
Loss of hair is sometimes a potential sign of Cushing's. Often there is a overall generalized hair loss/hair thinning. although you can get certain areas that are more pronounced than others. My Tuxie had patches of hair that thinned out more than other areas and had no hair regrowth. He was shaved for an ultracound and still had not regrown the hair after 2 1/2 years. Sometimes the skin can become very thin and in some cases of the disease it can begin to tear with little or no pressure on it.

Cushing's is considered a rare disease in kitties ( common in dogs) but personally I feel that is from under-diagnosing. The easiest. least invasive test you can do to test for Cushing's is the UCCR (urine cortisol creatinine ratio) test. This involves collecting a urine sample at home so there is no stress involved. The sample is taken to your vet and sent to an outside lab, such as IDEXX for testing. If the results are negative then no further testing is necessary. If the tests are positive or borderline then further testing is needed to determine if it is pituitary or adrenal based Cushing's. I can't find my receipt, but I believe the UCCR test was about $125 Cdn when I did it 2 1/2 years ago.


I had started Tuxie on Lantus originally but changed to Levemir a few months later since I found that he flinched a lot with the Lantus. Lantus is more acidic than Levemir and some kitties can "feel the sting" more with Lantus. However with the hair loss and open sores appearing it may be prudent to run the UCCR test to rule out Cushing's as well.

If you need more information please tag me and I will reply when I am on.

When I switched Oreo to Levemir, there was no change in his scabs, which have all gone away since his leg amputation surgery. I do not not why these scabs appear and then go away. It's happened several times in his life so I'm at a loss. For the record, I like Levemir better than Lantus. It costs a little more, but I use less than half the amount which saves money in the long run. It keeps his sugar more stable.

Not really over grooming....but a day or so before it happens, I'll see him getting picky with on spot, like it's bothering him. Then a later, he'll start running like he's trying to get away from it, and licking it like crazy, like he's being bit or stung by something. Then he gets a big oozing sore, and then he licks the open sore a lot until it starts to heal.

Ok, wait, just reading about cushings disease now. what I described above is what happens with the sores, but yes, he is also over grooming on the abdomen and front paws. still reading...

And :bighug::bighug:

Perhaps it started when he began getting Lantus because Cushings cats are usually diabetic. When the Cushings/diabetes started, you began Lantus. Or maybe it’s something else but IMHO, it’s worth getting the urine test done and then going from there.

Yes, they shaved a patch on his neck when were first looking at the diabetes. That was in February and it still hasn't grown back. He has also over groomed baldish spots on both sides of his abdomen and front paws. And then of course the sores that open up every other week or so. (which look just like the picture in the link you provided).

I'm going to do some more reading about this and contact my vet shortly. How did/do you treat for Cushing's?
 
How did/do you treat for Cushing's?


If it is PDH ( Pituitary Dependent Hyperadrenocorticism) trilostane also known as vetoryl has been used with some success in kitties. It helps to mitigate the effects of the overproduction of cortisol caused by Cushing's. In the beginning this requires regular ACTH tests to make sure the dose is not too high. Too high a dose can put a kitty into Addison's which can be deadly. Addison's is comparable to a hypo where you have to make sure the levels don't get too low or it can become a serious concern. If it is ADH (AdrenalDependent Hyperadrenocorticism) then surgical removal of the tumour from the adrenal is used.

Of course IF the UCCR test were to come back poisitive or borderline other tests would be required to determine what type of Cushing's it is, before starting any medications. With Tuxie who had PDH I chose not to do the medication, since the stress of vet visits would often aggrevate his chronic pancreatitis. He survived 2 1/2 years with Cushing's and crossed the Bridge over 7 months ago, but in the end it was suspected cancer that took him down, very rapidly towards the last days.

I used various supplements to help with the organs that were most affected...the heart, pancreas, kidneys. liver and adrenals. I also closely monitored his glucose levels and sometimes used unorthodox dosing approaches to deal with his wild glucose swings.

After reading through the links provided and some other info I looked up on my own, I am CONVINCED he has cushing's disease. He checks off every one of the symptoms listed. I am going to contact the vet in the morning to figure out our next steps. Unfortunately since him and his sister (RIP Shady) both got sick this year, money has gotten very tight with all the vet trips and medications. I'm not sure what I'll be able to swing financially.

A couple more questions, if I may? 1)You say you suspect cancer took him down. Are you talking about the tumor that caused the Cushing's in the first place, or something else? 2) Did your cat get the sores like mine keeps getting? If so, how did you deal with those?

Thank you so much for all the info you provided so far. I may be in touch with more Q's once I speak with the vet to see what our options are, if that's ok.

It certainly would not hurt to get the UCCR test done. It is non invasive and not overly expensive. That way you can know for sure whether Cushing's is a possibility. Usually the tumour on the pituitary with PDH is benign and not cancerous. The problem arises with the location on the gland and the effects that has on the endocrine system. The normal body feedback for regular cortisol production becomes "flawed" and cortisol is being produced and released on a constant basis. Cortisol is necessary for the body to function but over-production of cortisol stresses the body. However over time the tumour can increase in size and cause neurological problem because of the pressure.

A basic over all of PDH Cushing's, which is the most common type:

CD2.1.jpg


Another approach is to have an ultrasound done. A board certified U/S vet will be able to visualize both the adrenal glands, the liver, the pancreas, the kidneys etc. With Cushing's there is organomegaly ( enlargement of the organs). If the adrenals are both symmetrical with no irregularities, such as tumours, showing that helps rule out ADH. I originally had the U/S done and was given a tentative diagnosis of PDH by the U/S vet. My own vet did not believe that it could be Cushing's since she was taught that it is very rare in kitties. I pushed for further testing and the tests came back as borderline/positive indicating early stage PDH Cushing's. My U/S cost around $250 Cdn when I had it done. You can also do an MRI which is VERY expensive and can only be done at certain locations. I would have had to travel 8 hours to get to an accredited facility, so between the travel ( Tuxie HATED leaving the house with a passion and would become extremely stressed) and the expense I never pursued that approach.

I did not get a firm diagnosis of cancer with my boy. I had planned to do some more testing the week after I let him go, but it became VERY obvious that he was just too worn out and too sick and his quality of life was rapidly declining. We had the "talk" and he let me know that he was ready to go. If he had wanted to keep fighting I would have continued but he had reached the point where he was barely existing and had no quality of life.

Tuxie developed small sores, but had not reached the point where the skin was tearing and splitting seriously. He really loved his combing and brushing, but because his skin was thin and more fragile I had to be very careful about that. I bought a very soft brush and would carefully brush him with that.


The one thing I will comment on is that Bumpsy is responding much better to the insulin than Tuxie did. He ran in very high numbers, especially at the beginning and eventually reached 6 units BID over time. Then it became a problem of highs and lows. Since the tumour in PDH can cause waxing and waning with the cortisol production the glucose numbers can be very difficult to control. Although Bumpsy is not regulated he is showing a positive response to the insulin and is still in the early days of insulin treatment. This is the spreadsheet from Tuxie's early days...I did my S/S in sections, since I did not start it right in the beginning. Unfortunately I was not testing properly at the beginning so some data is missing.

Cushing's kitties are almost always diabetic because of the excess cortisol. If the tumour on the pituitary were removed the Cushing's and the diabetes would most likely have "cleared up" However there is also a chance that the tumour can reappear. With people surgery for PDH is the go to. However with kitties the surgery is very risky and expensive and there are few places that are trained to do it. With ADH Cushing's removal of the adrenal gland can "cure" the problem since the tumour is on one or both of the adrenal glands.

Bumpsy may very well not have Cushing's but ruling it out would certainly give you peace of mind. Hopefully some of the information I have given will be useful to you and if you need any more please do ask. :bighug::bighug::bighug:

My Summer has places on her that just show up here and there that look like your kitty. Summers will be raw and then will eventually scab over. Although i suspect she has cushings because of her skin being so very thin and her fur not growing back in places. Summers raw spots are unsightly and were upsetting in the beginning but i have learned to except it and just deal with it the best i can. I put neosporin on the spot if needed and that helps it heal. I have not gotten summer tested for cushings but my vet suspects it and she has the signs. I have not gotten summer tested because i choose not to treat her with the drugs and if she has to have surgery i refuse to put her through that. Both are not a guarantee and are costly not to mention. I do believe however this is why summer is on a high dose of lantus. And lantus does sting her at times too but she is pretty good with it. If i download some pics to my computer of summers raw spots, i will show you.
 
@Tuxedo Mom Thank you, Mary Ann, for this great post. You are amazing. I know your grief is still very palpable but you are always so selfless in helping others. :bighug::bighug::bighug::bighug::bighug:


Thanks Marje. The holiday season has been especially hard without my Tuxie here this year.

Most vets are not familiar with feline Cushing's or the basic testing protocols for kitties. I spent a lot of time learning about it and connecting with other petparents whose kitties had Cushing's so if I am able to help out I am happy to be able to.

Don't you worry about the pain it causes? Bumps seems very much bothered and in pain especially when the sores first appear. Once they start to heal, he's a little better about it, but I also worry about these wounds getting infected, and causing more damage (litter box, scratching, licking etc). He doesn't like it when I put a topical cream on it (he just licks it off) and runs away if he suspects I'm trying to reapply. I also worry about causing more pain by just trying to touch it to clean or treat. They look so painful to me. It just makes me feel so helpless that there is nothing I can do (or am trying to do) to stop them.

Even if he does has Cushing's, I'm not sure what I can do to treat him (financially and otherwise)...I just...I worry, about secondary complications, and of course, his comfort level.

Are Summer's as big as the sore Bumps has? Right now, he has two to fairly big open sores (one on each side), and two that are almost healed up. I would like to see the pictures if you get the chance.
