1 Dom 1 Passive

[Lashta]

Hello

We have 2 cats Tron is 1 year (Siamese Male) and Kainé is 6 months old (Maine Coon Female). We are on the Red Stage - however Tron refuses to share the LK or the toilet (we have it set up in two places in the bathroom). He seems to be forcing her to go potty in our bathtub .
Kainé is very passive by nature. When she has used the LK (we are usually in the bathroom standing guard - so she can go without interruption from him) Once she is done her business - Tron will (once unsupervised) fling her poop out of the LK. Today I had to plunk Kainé onto the LK because she was about to go pee in the tub because Tron was on the toilet doing his business.
We have reviewed the forums and we have been following the tips

-two LK spots for them
-treats for each cat when they go to the bathroom
-disinfecting the bathroom after Tron does a spray down (blue light is awesome)
-and I sit with Kainé when I get home from work in the bathroom to make sure that she can go in peace.

BTW when we had a regular litter box they shared it with no issues.

Any help or suggestions would be greatly appreciated.

Sorry noone has answered your question, it seems like you have read around here and tried finding answers and that is good. I'm not sure what else to suggest except that you have two setups...Have you read about the mock toilet method? : http://relaxedcat.com/
