Hey peeps, need some recs from the hivemind: I have a friend who is a wheelchair user who needs a carrier for his cat. His current one is a soft, back-pack like carrier, so the bottom doesn't hang level when he hooks it onto the back of his wheelchair, leaving his kitty smushed into the fold at the bottom. It seems likely this is a solved problem. Does anybody have any recommendations for a cat carrier to hook onto the back of a wheelchair?
