i always figured that teaching a cat/feline to flush the toilet was to invite incessant flushing, if only because cats are just irritating enough to do it constantly.
When my mom was a little girl, she had a cat that used the toilet boil without being taught. It also couldn’t flush though.
my old cat mickey taught himself how to use the toliet. My mom would put him in the bathroom at night, I cant remamber why she did, but my kittie started peeing in my potty (i was toliet training at the time) after we took the potty away it just started using the toliet.
