I got this automated toy for my cats:
My female cat really, really likes the toy. She grabs onto it and carries it around, even jumping on top of her cat tree with it held in her mouth, carrying the large base by the long "tail" moving piece.
However, she is a fairly small cat, about 9 lbs, and the toy with batteries is about 3 lbs. She moves slowly while dragging it; I'm quite surprised she was able to jump with it. I'm afraid she will hurt her neck. Am I right to be concerned, or are cats used to dragging around prey that heavy?
