Days of enjoyment
Thanks Pet Guys! We bought a "fisher" with this attachment on it as our first cat toy for our dearly departed Moby cat back in 2006. Now we have two new energetic boy cats, and our 1 year old Max fell in love with the attachment from that original toy. He would carry it around the house and fetch it! However, he would also put it in places "for later" and forget where it was, so we would be without it for days.
Now, though, we have a nice supply of them, and he loves each and every one of them. He still hides them from us (and himself), but at least we always have a few extra on hand so that the fun can continue.
ProsAwesome portability, great leather taste
ConsEasily hidden under couches and rugs (not really a con!)
