What's wrong with treating your pets like family?

When I say "treating your pets like family," I mean loving them, spending lots of time with them, talking to them, cooking for them. When someone asks me about my family, I say, "My pets are my family." My biological (for lack of a better word) "family" abandoned, abused, and did nothing but hurt me. I don't have people "family" or relatives, my pets are all I have. What's wrong with that? My dogs and cats show me unconditional love, something I never received as a child.
