Pet's update

I think there should be more pets. Things such as dog breeds, hamsters, reptiles, and amphibians. All pets should be like foxes, with the ability to sleep and sit and run around when they want ; but we'll still have the ability to make them sit and follow us. Also, they'd still have dye-able collars. Add-ons would be things such as pet food, toys, and other pet supplies. Another thing would be that they could get sick, and we could have the tools to get them better. We could also have the ability to get them sprayed / neutered. So what do you say? Can the Pet update be the next update?
