My cat, Spooky, is a little over a year old now (and yes, he is neutered). He has always used his litter box just fine. About 2 months ago, I was staying with my parents and we found a baby kitten, Toby, in our field and took him in. About a week or 2 after that, Spooky started running around while pooping. As soon as I realized it was Spooky doing this (I was staying with my parents at the time and they have the kitten and another adult cat, so I had to see Spooky doing it before I knew it was him), I took him to my vet. The vet said that he had coccidia and that was probably the cause. So we treated him for it, and my mom took the kitten to her vet and got him treated too. Then, about a week later, we had finished spooky's medicine (I was back at my parents at this point) and he started peeing in my bed. I took him and the kitten back to my mom's vet, and they said that the coccidia was gone from both of them but now Spooky had a UTI, so we treated him for that. He started peeing in the box again, but he never stopped his poop run. So, I took him BACK to my vet, and told her everything, and she said it was behavioral and gave me some tips to fix it. She said that the kitten, Toby, probably jumped on him while he was pooping one time and now Spooky is scared to poop. I agree with her, however, I have since moved back to my apartment, where Spooky is the only cat, and he has only gotten worse. He now poops on the floor and sometimes he will pee outside the box too. He doesn't pick one spot so it's not like he just likes to go in a certain area. I got a second box and put cat attract in it. Over the past week, i have tried 3 different locations for the new box. He will pee in one or the other (except 2 nights where he peed on the floor and in my bed), however, he will not poop in either. I also keep atleast one turd in each box so he knows hes supposed to go there, but he wont even cover them up. Initially, he would start in the litter box and go a tiny bit, and then take off and sprint through the house leaving poop in his wake. But in the last few weeks, he doesn't even try to start in his box and starts pooping and then walks or runs as he drops more pieces of poop. (He will sometimes pause and drop some, then take a few steps and drop some more). Also, he eats dry cat food and his poop is not dry, so my vet said that it is not constipation. She also did a full rectal exam on him and said everything was ok. Other than the poop, Spooky acts completely normal and has been eating and drinking about the same amount as he always has. He also doesn't seem stressed out, but I guess I could be wrong. Sorry for the long post, but I was trying to give as much info as possible. I need some good advice on how to make him feel safe with the litter box again, any advice would be greatly appreciated.
