What ever pet you get remember you will have to care for it. Those cute water turtles are easy to maintain as well as a nice aquarium. Seeing as I do not know what animal you like then it is hard to suggest them for you. Small kittens are cure as well as puppies. Birds are also cool.
I would get a dog preferably a golden retriever or a beagle. I have 2 beagles and they are amzing dogs. Golden retrievers are also good with kids so are beagles. If u want a guard dog than German sheperd.
