"My non-picky rat loved these, but more importantly, my incredibly picky rats also loved them! And they really don't like most treats or foods. Who ever heard of a picky rat? I have two of them.
One of the rats will not even take food or treats from peoples hands... except these. He will do anything for them, including tricks.
Only con is that theyre too thick to break in half to give to smaller rats, but the thickness also works to their advantage making a great item for them to gnaw their teeth down on."
