Answer:
What scientists might call your pooch.
I climb trees but I’m not a cat I hibernate but I’m not a bear I eat nuts but I’m not a bird I’m a type of rodent but I’m not a rat I have a bushy tail but I’m not a fox
I have legs but seldom walk; I backbite many but never talk; I seek places that can hide me because those that feed me cannot abide me
It's small but larger than a bee, And agile as a flea. It humms but does not buzz, And it's not covered with fuzz. It is a small collector, Of juicy flower nectar.
People take me on walks and I run and have fun. What am I?
Who makes it, has no need of it. Who buys it, has no use for it. Who uses it, can't see it. What is it?
