A female in heat will mate with as many male cats as are in the vicinity when she is in heat. A male cat can impregnate as many female cats as are available in a night.
This is how kitty mills operate.....one of my guys rescued from a mill is really
very interbred and has the physical problems to prove it can go so wrong.
