After he ate this morning, my male manx used the litter box and then he got out and seemed to be straining to poop on the floor. He wasn't crying out or anything, he just looked like he was trying to poop. The other day we found a poop nug in the hallway that also may have been from him (we have two other cats and it was found in the morning when we woke up, so we don't really know what cat it was from) Sometimes he does have a problem because he has no tail to get the poo out and it falls off after he has left the box. (sorry TMI) He also threw up a hair ball right after. He hid under the couch. I am worried for him because I know sometimes male cats can get crystals in their urine that causes blockages or he could be constipated? I had to go to work and I am worried that he is having so much issues. He is eating and drinking. Has anyone else experienced this?
