I live in a small two rooms apartment (living room + bedroom) with my girlfriend. We adopted a two-years-old rabbit in September and, after the first two weeks, he is a very easy-going rabbit: he doesn't chew things he is not supposed to, poops in his litter, has good appetite and he is friendly (not playful, but definitively not scared) even with guests. The only problem that we did not manage to solve, as you can guess, is that he often pees on the bed during night.
He is allowed to wander in the apartment during night, because his favourite place to sleep is under the bed, but he often jumps on the bed to sleep with us. Unfortunately, when this happens, one out three times he pees.
What we tried to teach him not to do that are these approaches:
In the moment in which he does that, we strongly (not shouting) say "No + his name!", and we take him and put it down from the bed. Sometimes, we close him in the living room (so, free to wander everywhere but the bedroom). Unfortunately, sometimes when he does that we don't wake up, so we cannot do that immediately.
When he pees in the litter, we give him a treat.
It's months now, but we don't see any improvement. Is this the right approach and, if not, what is an effective approach?
Although similar to this, in my case this happens at night when we sleep, so two problems arise: sometimes we cannot wake up and so cannot be constant, and second of all we cannot make loud noises.
