i am using tidy cats scoopable i have used it since i got my first cat years ago and they are all healthy

i have 3 cats and 2 litterboxes for them but all of them pee in my bathtub and not in the litterbox but will poo in them the boxes are cleaned everyday how can i stop them from doing that

i have a few rabbits and have themin one of my bathrooms i dont use untill the below zero weather is over and my dog keeps going after them what would be the best way to get him to stop the door dont latch so i have a baby gate but he jumps it please...

does anyone have any ideas on how to get a cat to go in the toilet rather than in a litter box
