Too many cats spawning everywhere

My villagers are not breeding or anything,they are all separated.  Before fox update there was a similar problem - in one room(5*5*5) iron golems were spawning like mad. If I was staying for a night afk, I could find about 20-30 in one place. but I was not worring about it, because it was easy to kill them all and they were in one tiny place,not everywhere. Honestly, I was kinda busy to think about it.  But after fox update,these cats are just killing me 😞. 

In MCPE Windows 10 PC Beta v1.15.0.51 and v1.15.0.53 cats are spawning in abandoned (zombie) villages. 

Cat population workaround: put the cats in a fenced area on the outskirts of the village. This will stop the cats spawning. If you kill a cat another replacement cat spawns. 

Can confirm this issue on MCPE PS4 1.14.41 SO MANY CATS! Wayyyyy more than 10, more like 40-50. I will note that the world was created in the old "PS4 Edition" of Minecraft then transferred over using the in-game transfer tool.

If anyone having this problem is able to provide a world download that would be helpful.

I have this issue. Large number of cats spawning over time. Uploaded the world to google drive because it's 250 MB. All the beds are under the floor inside the library.

I forgot to mention that this is on Win 10. I just noticed the bug report is for Xbox.

Data from the sample world provided by Klaus Klein:

• Village goes from -31, 55, -88 to 33, 79, 23. That is default X & Y dimensions (64 X and 24 Y). It's extended in the Z direction to a length of 111 blocks but that's not excessive.

• By my count there are 77 beds within the village boundaries (75 under the library, 1 for the farmer in the crop farm, and 1 in the player's house that is within the village boundary.)

• There are 29 villagers and 155 cats registered to the village. That's about 2 cats per bed.

• All of the other villages in the world are hundreds of blocks away.

None of this explains the overspawning of cats.

Update: after running a command to kill all cats and then waiting about an hour, I got 2 iron golems and 214 cats. Evidently the global mob cap of 200 does not apply to cat spawning.

I have reproduced this bug in a small test world: 

. The world consists of a village on top of a platform, with beds on two levels. There is a hole in the middle through which the player can fly up and down between the levels in creative mode. At present there are 88 beds, 38 villagers, 3 iron golems, and at least 27 cats in the world. If you open the world and let in run, cats will continue to spawn. Here is a picture of the lower part of the world:

What is happening in both the test world and the world provided by Klaus Klein is that new villages that overlap the cat village's boundaries are repeatedly being created and deleted by the game. These villages have no villagers, but cats spawn in them while they exist. The cats then join the existing base village because they are inside its boundaries, and the newer village is deleted after a period of time (presumably because it has no villagers). (A cat can be registered to both villages for a period of time, but I can't say for sure if it always passes through this step.) The root of the problem is that the game creates new villages overlapping existing ones whenever there is a certain number of unclaimed beds--I have not tested this number precisely, but I've seen comments in village tech discussions saying that 32 unclaimed beds will generate overlapping or "stacked" villages.

Here is a screenshot of data from Klaus Klein's sample world showing that the same cat in a transient villager-less village (on the left) and then in the base village about 4 minutes later (on the right):

Here is a screenshot showing the location and timestamps ("Tick") of the transient villages in his world at the same times as the cat listings shown above. (Note that the window on the left in each picture is the same village at the same time, the window in the right shows the base village in the first picture and the transient village at that time in the picture below.)

The minimum conditions for infinite cat spawning are 2 villagers and 36 unclaimed beds.

exhibits the bug with minimum conditions. It contains a black box housing 2 villagers and 38 beds that endlessly spawns cats. It keeps the cats contained in a small walled area surrounded by lava. It has a scoreboard and command blocks set up to count the cats. Press any of the buttons on the top corners of the black box to get a count.

Windows 10 PC v1.16.0.59 Beta. Since the last update, there are more cats spawning than beds in my village(s), see attached Overrun with Cats screen shot 1 above.  I have rounded up every cat in the village(s) and put them in a pen, but more cats spawn, see attached Overrun with Cats screen shot 2 above.  In previous Betas, the containment of cats in a pen stopped the spawning of cats, but that is no longer the case. I wish the option to have cats or not was still in the game.  

@Bubbah Doodah would it be possible to get a copy of the world where this is happening?

@GoldenHelmet, here's the link to the latest export of my world: New Coastal Village v1.16.0.59 20200504a

The above screen shots were made at the village located: x=1370 y=71 z=138.  For every cat I put in the pen (back of the village) or put the cat outside the village, a new cat spawns.
