A new toy to help pets deal with anxiety

[Catherine]

There is a new toy that is designed to keep pets occupied and less anxious when they are alone. It is a mat that can be chewed. It can have food treats rubbed or poured onto its surface and it takes time for the pet to get every bit of the tasty treat.
Pets get so preoccupied with the treat, they forget you have left them alone.

It looks interesting. Do you think it would work? 
Food is the key to a lot of feeling secure. A big bowl of food would work, but your pet could end up really fat. The pet only gets a bit of a treat with the mat. 
It would be great if it worked.
