Cats randomly teleport to the player, often within nonsolid blocks, from my mob farm

Bug: Cats randomly teleport to a nearby location to the player when the chunk the cat is in is loaded.

Storytime! So, in a (is it a or an?) SSP world, I was building a hostile mob farm, but I got really lazy, so I used /summon Ozelot <x> <y> <z> to get the cats, and I used some NBT Tags: Owner and CatType (was I forgetting one?). I went back in survival mode, and they started teleporting to me, usually inside nonsolid blocks (chests, ender chests, fences, halfslabs, stairs, grasspaths et cetera), especially when I was standing on blocks ≠ 1 meter tall. (Chests, halfslabs, fences, et cetera.) I realized they might be killing chicken jockeys, since they usually survived, it didn't make sense that there were still raw chickens (raw chickens? why does that sound weird) in the hopper. They were also teleporting to me when a mob attacked me, but that might be a totally different bug. It happened 1 time with dogs and about 10 with cats, and the dog had an orange collar, so I assumed he had came from my old mob farm that he had glitched out of by a mob pushing him. There were about 5 in my storage room, which I visit no more often than my mob farm collection area, which there was only 1 in, and the floor is made of slabs in only the storage room, and it is very odd there would be so many in the storage room.

They also have unusual behavior after teleporting: See MC-96370.
