You can put his dinner in them if you feed kibble - stuff 4-5 of them - keeps them busy for ages. Lately I have been putting a little cooked meat in the end then a sardine and then a bit more cooked meat and sealing the ends with duck pate - mine are such spoilt little babies...............This keeps Roddy busy for a good hour - honestly - he licks and licks at it trying to get the food out.
