The new kitty is settling in.  I’m pretty sure he’s a neutered male.  I will check again to be sure.  He’s settling in and even YinYang is not so actively hating on him.  She doesn’t like it but at least isn’t stalking him and snarling at him. She just glares at him from across the room.  I set up a cat box in the hallway just in case and about 3:30am this morning he used it while I was in the office.  Aaaugh!  I want him doing this outside, I will not have a box in the house, this had better just be a temporary thing.  But one reason I think he did was because yesterday I was wondering if I should get him checked for worms.  So me discarding his evidence gave me the chance to inspect it and no worms yay. I typically get my cats their first shots when they are neutered and that’s it, unless they go back to the vet for something.  Then the vet requires their shots get updated.  Otherwise, I think them eating their partially wild diet keeps their immune system strong.
