Exactly.
And I have a neighbor I love, who pretty much does that. She does exotic cat and miniature Italian greyhound rescue/fosters. As a result, she has 10 cats and (I lost count recently) 5 or 6 miniature greyhounds. Plus chickens, roosters, a few quail, a few ducks, a couple of rabbits, and she did have two rats for a while (Timmy and Jimmy) because she found one with deformities and felt sorry for it, so found it a friend and built them a dollhouse. I love her. And I would be her if I fostered.
Luke looks like a doll.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
