Minecraft wiki entry for Cat, associated text: in Bedrock Edition, a village periodically spawns stray cats to fill a quota of 1 cat per 4 owned beds, up to a maximum of 5 cats for 20 or more owned beds. Only owned beds (those currently claimed by a villager) are counted for this purpose. All cats within the village boundaries are counted, including kittens, cats that wander in from outside, and even tamed cats owned by a player. If the number of cats found is short of the quota, the village tries to spawn one cat or kitten within a volume of 16 × 6 × 16 blocks centered on the village center. (This is the same volume used when a village spawns an iron golem.)
