My kitty might have IC too
Not looking for advice--i just think the coincidence of me and Triscuit both maybe having IC is interesting.
Triscuit has been drinking and peeing more than typical for a cat, so he had blood work and urinalysis done recently. His urine was quite dilute and had some blood in it, so his vet gave him an antibiotic to treat as a UTI. Litterbox visits decreased initially but have now increased again. I spoke with his vet today to see if he should return for a followup. They do want to see him again to rule out major problems, but the vet mentioned he could have Feline Idiopathic Cystitis which presents as urinary issues without a clear cause (seemingly stress, nervous system related). FIC is very similar to IC in humans. It's been quite interesting to read about.
IC and FIC unite!
