His appetite is great - actually, he is eating quite a bit!
His bathroom habits are fine - regular with no issues.
He is a bit lethargic - he won't play with toys, new or old, but that has been for a few months now. I should tell you that my sister moved in with me back in July with her 3 cats and that's when the play habits changed. He was marking EVERYWHERE and often, that is why he is on the meds.
Back to being lethargic though... yes, he is. He also has taken to sleeping under my bed vs on top with me, and now he occasionally will go under the couch or ottoman - not his normal behavior. He's been doing this on and off for the past 2 weeks.
I believe I also noted to you that his is FIP positive.
