I've been amazed at the number of customers who have told me that their cats aren't particularly fond of collars, but when they put the Calvin Collar on, they seem to enjoy it. It makes me feel like Calvin's special spirit is with each collar.
However, a non-scientific study was done with the three cats shown below. My good friend, Barbara, bought three collars for her sisters' cats. See if you can tell which cat is not thrilled about the collar or getting photographed!
This is beautiful Callie in the For the Cure Calvin Collar.
Here is handsome Gizmo.
