One of my cats, Rosa, was just diagnosed as diabetic yesterday. I feel terrible - she's been eating Royal Canin Urinary SO dry food for years on veterinary advice after having bladder stones removed in 2007 and now I'm reading that this might have caused it. She'd had blood work done in August prior to having her teeth cleaned and one removed - everything came back fine then so now I'm wondering if that procedure might also have contributed to this. In the last few weeks she'd gone from being a happy, lively 11 yo cat to very lethargic with some digestive issues and for some reason constantly having kitty litter glued to her paws - we changed the brand of litter, little did I know that this might be an indication of sugar in her urine. I'd taken her in to see if she could go back on the SO food as she'd started being a very picky eater and was losing weight and the diagnosis came as the result of a urinalysis to check for struvite crystals. We're back at the vet tomorrow for blood work and to get her first insulin prescription. Right now I'm feeling guilty for giving her food that might have caused it, getting her teeth cleaned and maybe causing inflammation that way and wondering what I could or should have done differently to prevent this and how to get her accustomed to twice daily injections - she's almost impossible to treat with any sort of medication after being on antibiotics and metacam for a number of weeks when she had the bladder stones. I also feel bad because we're on a planned personal business trip from the middle of next week so she's going to have to go to a medical boarding vet before she's even had a chance to get used to the new regime. She and her twin were feral as kittens and don't deal too well with being away from their familiar surroundings but this is going to have to be the way it is now anytime we have to be away ourselves. Desperately looking for any advice on how to get her (and me) through this.
