Most of them really don’t mean any harm it’s awful. I actually bought a cat from a hoarder, she had somewhere between 15-20 cats on the second floor of her small home some of the cats were literally living in travel kennels stacked in the laundry room. She was being evicted and had to rehome her cats which was devastating for her. The cats were absolutely better off being rehomed but it’s still heartbreaking to see. My cat was one of her favorites and was evidently quite pampered he came home with us to continue a long life of pampering.
