Dogs: Micki and Jack (the other three are family dogs)
Cats: Motchka (Jasper and Batman are family cats)
Guinea pigs: both mine
Gecko: mine

The pets that are mine I care for financially. Pay for everything for the guinea pigs and gecko, the cat and dogs I pay their vet bills, licenses, etc. When I talk about my dogs though I refer them all as mine because I was their main caretaker (before I left, lol).
