Aw that's so cute! We got a kitty stroller for ours and he loves sitting in it and napping in it. So we hope, come spring, he'll be happy to be inside it and chillax as we walk around!
I worried about the suction cups, too. But I decided to try it as there is no other way with my apartment, if I used ones that have support from the wall, I could not get on the otherside of my bed to make it.
