Toilet Training Cat Peeing in Toilet Day 50 (turn up your speakers!)

Finally! Day 50 of cat toilet training 3 cats. 5 year old Charlie gets it! He pees over a 3" round hole in the tray. He positions himself over the hole to pee straight into the water. He seems to prefer peeing into the hole as opposed to peeing on the flushable litter.

Unfortunately, Boston, my Exotic Shorthair cat does not like the toilet and is moving at a much slower pace. I've had to revert back to the 1 1/2" hole tray because of Boston.
