Thought this was a fab toy when I saw it so I ordered one.
Another excellent delivery from this seller, 5 days earlier than delivery estimate so am really pleased!
It's bigger than I thought it would be and made of nice robust material. The underside of the caterpillar is thick, soft fluffy-ish fabric, and his back is cotton with a sort of partly-shiny robust coating. The body is the part that lights up with red flashy lights. I was wondering how robust it would be because of the wires in the body but you can hardly feel them, as the outer fabric is so tough and fairly thick, so it will stand up to a fair bit of play without any damage to either kitty or the wires! Obviously keep checking just to make sure so kitty doesn't put himself in any danger! The main power unit is in the caterpillar's head and that is so well stuffed and padded that you can't feel the unit at all, so it's perfectly safe.
Kitty really likes it. He likes me to hide it under the rug but prop the rug up so he can see it flashing and dive under to fetch it out. Really good fun for him, and am looking forward to seeing him play in the dark with it!
Another really well-made and good quality Petstages toy, would recommend!
