Frozen treats to make for your cat

[Catherine]

In this hot weather it is tempting to give ice-cream to you cat, but ice-cream can make a cat sick.  It would be better to create a frozen treat you cat would like, that would be good for it.

I could picture a cat licking "ice-cream" with tuna in it. Somehow I think that flavour will never make it big in the grocery store.
Cats like a cool treat so this might be the healthiest way to do it.
