While his message is a good one, we do have a responsibiility to care for the animals we take on as pets, I think he is shaving the ice a bit thin with the simantics over saying i own or I care for. Ultimately the result is that the animal lives at my house in an enclosure I provide, and eats food I give it. This is the same if I say 'I own the pet" or "I care for the pet". The difference is in the attitude toward the care I give not the word I use to describe ownership.
