Jess, wonderful story🤗
I never knew that about cats, I have seen my daughters cat – and he has been side slit pupils!

Fascinating Jess. I’d never thought about the pupil design of predator or prey…. always something to learn.

Amazing information. The Londololozi blog is one of the few sites that make research information appealing❤

Thanks for digging into this topic and sharing what you’ve found out in such a clear and concise way.
