It is a Civil Rights Violation for local governments to not provide equal but separate park facilities for pets
based upon species. local governments cater to DOGS only. This must be prosecuted in order for change to occur.
Sounds like what you are looking for is timeshare property for your cats to enjoy.
Get a group of cat owners in your area to buy an acre of land with grass and mature trees and water,
cyclone fence it off, build some nice landscaping with running water,provide each owner with a key to get in...
I drive to a nature area with a creekbed, put my cats in a dog cage and lay it on a pull cart, and pull them to where we are going.
Once there, I lower myself and pets on a rope (tied to a tree) so we can climb down to the creek bottom, which has a sandy beach.
Then I let them wonder around...
