Cats are really quick learners. Chewy learned to go in & out of her toilet in less than 5 minutes! Mom knows some ppl like teaching their cats to use the humans' toilet, some even teaching the cats how to flush (but it's not good as some have commented that their water-bill will increase since the cat loves lookin' at the toilet being flushed over and over again). But Mom just thinks it's pretty un-natural for them & deprives them of their natural instinct to ''dig'' after they're done with their pee/poo.
Here's more cutie chew!
