How to do pooling with different objects?

Question

Unity

Good afternoon. There was such a situation. It is necessary to generate with random parameters, for example, a cat. They will be generated and go somewhere.

I wanted to use the pool, but it's only for identical objects. So I'm scratching my head, how to optimize such a process? I've been searching the internet for information on this topic, but nothing so far. I won’t have anything like 1000 bullets fired at the same time, but I don’t want to load the game once again.

I will be glad for any help! Thanks
