It's hard to answer that question because none of us know you. I have 3 chinchillas and they are great, but if you are looking for something "cuddly" then a chinchilla is not what you want. They are very active animals and don't sit still too long. They also need a large cage and I don't know how much room you have. They aren't a pet you would want to keep in your bedroom as they are pretty loud at night.

Hamsters and gerbils are great to, but I personally like rats better. Rats make wonderful pets.

I don't have any personal experience with coatimundi.
