I have the same one that Yorkiedaze has, but Max can't really get into it...well, he COULD if he was really motivated and there was food or something in it, LOL..but it's kind of high. I know this isn't a soft sided one (I LOVE the one Kathy posted), but I just ran across this one that I thought was cute and someone else might like...and it's so inexpensive too!
