I started cat sitting and dog sitting for my neighbors when I was in elementary school, and still do. I have four cats of my own and used to have a dog, so when I take care of other animals I make sure I treat them the way I expect my friends to take care of mine. It's important for me to make sure the animals are happy and healthy and don't feel alone. I've dealt with having to give medication to my own animals as well as other's. I don't mind spending extra time with them in order for them to feel a little less sad while their owners (or parents as I like to call them) are away.
