Cat pooping in the rabbit hutch

[olivesnutsandcheese]

Gah the cat has been attempting for a few days before finally succeeding in a stinky turd in the rabbits hutch.
The rabbit has been an indoor bunny since December. Cat not impressed at all and gets very jealous. Do you think she's making a point to shit in the bunnys bed?
I need to keep the flap down on the hutch now as soon as I let the bunny out in the morning. Both pets are locked in (different) places at night.

What do I do???

It's probably the ammonia smell that's appealing, rather than a dirty protest.

Probably thinks it's a litter tray?
