Jeg har egentligt ikke et direkte oversættelsesforslag, men jeg tror ikke nødvendigvis det er et egern, som Inge forslår. Se nedenstående.

"SQUITTENS

"Squitten" is a term used to describe supposed cat-squirrel hybrids. It derives from "squirrel kitten" meaning the offspring of a cat which has mated with a squirrel. The term has also been used by a cat owner whose cat nursed and reared an orphan squirrel baby alongside her own kittens.

A squitten is described as cat-like with a plumy tail and short front legs with paws resembling hands in which it can hold things. It sits on its haunches like a squirrel and can climb trees, but when on the ground it moves with a bobbing or hopping gait. As geneticist Roy Robinson reminded his readers, cats come in different colours and varieties - you cannot rely on appearance alone to identify a cat as a hybrid."

I know this is too late, but I think this could be "cat squirrel" which would be "rød-brunt egern" which we don't see in North America.
