Is there any shade when looking at the cats or is everything in the sun?

There are many trees and spots to step into shade.

We didnt take a tour bus. There is shade. There's also an air conditioned office with a round table you may go in if you get over heated. They sell water, Gatorade and a few dicferent flavor Soda Pop also.

Under the sun. There are some large trees that provide some shade, but no sheded/shaded pavilions/pathways. Best time to go is early morning or evening.

The grounds are covered by large trees that give a lot of shade. There are exposed areas, however.

All answered here what i would have said

Yep you can find shade. and there are randomly placed park benches. And if you take the tour bus you don't have to worry about sun

Both, but you can find shade easily
