actually my cat did this. He recently stopped. Im not sure what is up with this.
Cats will eat different food, it's just like how they eat table scraps, or eat grass. It's a mental thing. We will truly never know why they do what they do.
Another reply here that tells you it's normal.
Over the years, I've had 3 dogs - all of them ate cat food as well as dog food. I guess it doesn't really make a difference to them.
My dogs have eaten cat food, but never the other way around. At least that I am aware of lol.
I have heard of this happening quite often, and everyone says that it is not a big deal.
LOL some dog food tastes lika a cat food. thats my opinion.
