Cat's Spawning is broken too massive quantity

Hello, we play in multiplayer and we found that cats sapwn without stopping and moving away from the village where each team of custom players its village, we are 378 cats for 4 occupied villages instead of 4 * 10 = 40 which should to be in each village?

 

Another precision it's so the same problem for the iron golem, show screenshot in attachment, with 64 villagers i have more than 178 iron golem, all migrate in the same point, like cat and animals
