As paid experience, I have cat and house sat for a family in San Mateo, Ca., going daily to feed the cats their soft food, refill their regular food and water dishes, give them some TLC and let them out (2 of them are allowed outside) for a while to get some air.
I, personally, have always had a cat, since I lived in an apartment. I do, however, love both cats and dogs and being able to interact and care for them. They are sometimes more human and/or humane than some people are and need the same love and attention that humans do.
