Yeah, we've tried both the skineez and the Kong "Wubbas" as they're called. Hahah. The skineez are lucky to last a half an hour around here, but the Kongs are a little better.
I just had to throw out all his toy "carcasses" because Keely has been getting into them... so I figure I should get him some replacements.
Maybe I'll get them a couple Kong stuffies.... Though other suggestions would be appreciated!
