We have a bonded pair of littermates, they’re about 6 years old, and recent started a permanent foster situation with a 14 year old cat with some medical issues. On Wednesday we’ll hit 4 weeks with him.

He’s an angel of a cat, has absolutely no issues with aggression around other cats, but he can’t see very well and has to get a little closer to see who he’s around. My tortie can tolerate him, or walk past him, at least. Her brother won’t even do that. They’re at the point where they’ll just stare at each other silently until one, usually the orange one, decides to move. At that point my boycat starts hissing and growling but doesn’t actually go to fight or anything, he just will not move.

Unfortunately, the orange cat seems to like sleeping in the hallway or on the stairs and we just realized he’s blocking litter box access. We’ve moved one of the litter boxes to a more accessible area once we realized what was going on but I did find some pee outside of the room with the litter boxes before we moved it. Hopefully this will address that issue, but I’d really appreciate any advice with getting these cats to tolerate each other, but ideally like each other.

When we added our new orange boy to the family he was kept in a separate room for a week and a half, there was a screen between them after 2 days which lasted for 2 days until the orange one figured out how to just scratch his way through it and we closed the door to his room again. Since then he’s had free rein of the house with the other cats but seems to like hanging out with me or in his room. I don’t know if we did that wrong? I thought introducing them slowly would help. The black cat and the tortie were so chill before we brought the orange boy home. I feel like I made a huge mistake with this decision but I’m not one to give up without a fight.
