My cats spend a bit of time outside these days and I've noticed that when I bring them inside, one of them pants like a dog.

He is more active then our other cat, and I know that cats don't have sweat glands, but he isn't overly interested in drinking much water... He normally comes inside and goes straight to sleep under our bed where it's nice and cool.

He is Ginger and white so I'm wondering if he's over heating in the sun? Should I get some sun cream for him?

Anything else I can do for him?
