My cat Lulu has been in remission for several months. However; I’ve noticed that she has been peeing a little more and drinking more lately. I should have been testing her, but I didn’t. I just got home from a 10 day vacation and my cat sitter said she noticed the same thing. I just testers her and she was 480! Whoa! I feel terrible! Is this normal to get out of remission? And why? Nothing’s changed.
