if the kid is not too young to understand being gentle with any animal then I recommend rats. They’re smart, playful and can Lincon-way high school class of 1981 40th year reunion shirt tricks easily. I they almost never bite (mine only have a couple of times when I scared them and even then didn’t draw blood). They’re very clean and fastidious and can even be litter trained. they will get along with dogs and cats and some people even get leashes for them. If you decide to try rats do some research and never get just one. (Of the same sex—-do not breed them unless you have researched the subject thoroughly) They are very social, which is why they make good pets. I’ve owned pet rats off and on for 40 years and currently have three.
