Our 15YO male kitty was just diagnosed today (he's at least 15). He was a partially grown rescue years ago so he could even be a little older. He was just taken to the vet this morning because I noticed he was drinking and urinating more. Vet is keeping him overnight and I'll get instructions on insulin and diet tomorrow. BUT, I want to know, can you get insulin other places besides the vet?? The meds at the vets are usually overpriced most times compared to retail or online. Any other advise or things to know? They are already talking about putting him on a special food...my feeling is he is 15, should I feed him what he likes???--I have tried "special" diet food with him in the past for other ailments and he HATES it and takes me months to use it up...... Any advice appreciated or other things I should consider. I am starting to read horror stories online about pets urinating throughout the house and hypoglycemia. Am also reading stories of people who have forgone the treatments and just fed a special diet. I have somewhat of an understanding of diabetes with humans as I have worked in the medical field but do want to go to the Vet prepared before doling out hundreds or thousands of dollars without having a complete understanding of what we're up against. Thanks!!
