My new cat generation in the world

My world new cat generation conditions:

1, mainly because the number of existing animals in the reproductive area cannot exceed the capacity, and a small number, such as 1 1 in 272*272, squid and bat are measured separately.

2. Ordinary animals always grow on grass squares, cats can also grow on fallen leaves, and mushrooms only appear on mushroom island.

3. Most biota can produce sheep, pigs, chickens and cows, forests can also produce cats, coniferous forests and mountain forests can also produce wolves.

4. Deep-sea, river, desert and beach biota cannot produce animals, but only aggressive creatures and squid.

5. Mushroom biota can only produce Pleurotus ostreatus.
