Hi, don't know if I'm being a bit too paranoid but worried about the furry guy. He's a recently diagnosed cat and while at first he seemed to be doing ok, the last couple of days have been a bit difficult. He doesn't seem interested in eating the wet food, even the ones that he used to really enjoy before the diet change (we're almost 2 weeks into the diet change). He also hasn't pooped in over 48 hours. His insulin dose did increase from 1 unit/12hours to 2 units on Wed evening (today is Sat.) and the temperature has been much higher than usual here (90 degrees which is really warm up here) with no AC or anything. Is this a normal part of the diet adjustment? Should I be in to see a vet and if so how urgent is it? Thank you for any replies!
