Just wanted to share a funny story from this morning. I bought a new bag of World's Best Litter for them to try. I also received a humongous litter box with a top (brand new!) from a neighbor, perfect because my monsters are too big for the standard large litter box. So I moved their (used) litter to a different part of the apartment, set the new one up (top off) in the regular spot, and poured the new litter into it.
I'm used to gray litter, so this being a peachy color kinda threw me off, but who cares about the color of litter as long as it works! Both my cats were watching me curiously. When I was done, I picked one of them up (the one who is... peculiar about the litter he likes) and plopped him down in the litter. He leaned down, started sniffing it... then took a bite. He promptly spit it out and glared at me as if saying "Mom, this is the most disgusting cereal you've ever bought me." Then he walked to his old litter and decided to use it right then there. I swear the other one was laughing.
Pains in the asses, both of them.
