Cheesie my precious 8 yr old brown tabby suddenly developed difficulty walking. His four legs splay out from under him. He was weak and just layed with head down on the side, blank stare in his eyes. He ate very little. Stayed up with him most of the night. He mostly just layed on the floor with his eyes part open. Monday morning cancelled all plans and called his vet who couldn't get there till 430. All that day I could not get him to eat or drink. He tried a little bit of tuna that I laced with q10. He promptly vomited up that little bit followed with some dry heaves. Vet spent a lot of time with him. Body temp was only 96.4. Vet was strongly suggesting euthanasia but also left an antibiotic for a possible urinary tract infection. He took it well. His appetite is back, he lays with his head up and use his litter box. Not fully him self but more alert. But he still cant keep his legs under him. Vet attributes this to low potassium. What could cause this and how can it be treated? He has been on insulin and zoboline vitamins since July 2016 sugars are usually in the high 300 range. His insulin resistance has been attributed to acromegaly. He is now up to 10 units twice a day and lowest reading has been 198. Can cats have thyroid storm from infection like humans? What else could cause his sudden walking disorder. Love him much but trying to keep him out of stressful hospital stay. Thanks for any advice and prayers.
