We have just a cat, a hamster and a few fish. We don't have a lot of time otherwise we'd have a dog, but the time limits mean that we need independent animals.
We don't have a pet because my daughter is allergic to furs. We found that when we visited a friend with a cat. My daughter starts sneezing and coughing after she played with the cat.
She really wanted to have a kitten but we can't have one because of her condition.
