I like the second picture in the article... he looks so determined!
I almost got Paizly a cart. But for several reasons, I decided against it:
#1 - she's such a scaredy wimp, that I'm sure she'd think it was some monster that got ahold of her and trying to chase her down
#2 - they say not to leave those things on all day, just for a couple hours of exercise. She gets around just fine by scooting around pulling herself with her front feet (and it's not like she really goes anywhere. Food bowl, litter box, back to bed). Other than a bald belly from rubbing/dragging on the floor, she doesn't seem to suffer any bad effects from it.
#3 - they're expensive! $200 was the cheapest I could find... and that will buy lots of her special cat food for her finicky stomach, instead!
