Right now I have a fish tank and a dog that is a foxterrier mix that I adopted from the animal rescue league. I used to have a lot of different pets, I had: gerbils, guniea pigs, 2 large birds, and various cats and dogs.
I currently have two cats. One is a calico, and the other one is a long haired black cat. They are a lot of entertainment. They are still kittens so they are really playful.
We have a dog and several cats. Four cats we actually adopted while the other two just came to have a meal along with the others. Since then they won't leave and decided to stay.
I have had a turtle, a few dogs, a couple of hamsters, cats (still have cats) and I have some fish now. The cats love the fish. we have, They sit there looking at the fish all the time. It's rather fun watching the cats watch the fish.
