Animal like cat dog horse have an appendix?

You're asking if cats, dogs, and horses have an appendix. Here's the breakdown:

* Cats: Yes, cats have an appendix.

* Dogs: Yes, dogs have an appendix.

* Horses: No, horses do not have an appendix.

Why the difference?

The appendix is a small, finger-like pouch that extends from the colon. It's thought to play a role in the immune system, but its exact function in humans and some animals is still debated.

Horses have a different digestive system than cats and dogs. Their digestive system is designed to efficiently break down tough plant material, and they don't need an appendix for that purpose.
