Maynard's poop...

My cat Maynard got fixed on the 1st of Feb. which was about 3 weeks ago. Since then his poop hasn't been the same. It's not really diarrhea but it's not solid. Before the surgery it was always solid but since it's been what I described. His diet hasn't changed and about a week after he had the surgery his appette went back to normal as well as his water intake. He did eat during that time but not his normal intake. He doesn't seem to have any problem pooping but it's just not normal. In the next week if it doesn't go back to normal I will can the doctors. But I just wanted to know if this has happened to anyone elses cat. Thanks.

I would be talking witht the vet... has he been outside??

No he hasn't been outside. He's an indoor cat. Aside from his poop, he seems healthy. He's acting completely normal. But his vet said cats hide their problems much better than dogs, sometimes you don't even notice anything until it's too late. I think I'll be calling the vets soon.
