Yeah he is sitting downstairs! Although after I posted I went back in and he was sitting upstairs in his litterbox and he did some poos which still look normal. Then he went back downstairs and flicked a toy a couple times with his nose then sat in the corner again so that’s a slight improvement. 

I gave him his excel pellets which he finished off. Then some leafy greens and a grape and a little piece of broccoli and he ate all of it. He looooves banana so might try that too.

I may be overreacting but anything that is out of the ordinary worries me! He’s normally very spunky and energetic at this time of night

Yeah my cat also frequents my bedroom where my bunny is. My cats never been an issue in the past but that could be a possibility! I’ll keep an eye on them two. My rabbit was a bit chirpier this morning so I don’t think he’s sick which was my main concern!
I’ll see how he goes today

Just an update. Bruce is much perkier tonight! So that is good news.

However, I have noticed he’s now started peeing outside of his litter box too. Which makes me think it could be that he’s not liking sharing with my Cat all of a sudden?

I’m not sure what’s changed. And it’s a tricky one because my cat owned my room long before my rabbit came in so I don’t want to completely ban him from my room (I could never do that). I might try keeping him out during the day time and letting him sleep with me on my bed at night time, I normally cover Bruce’s cage with a blanket at night time as well.

Any tips will be appreciated! I hope this isn’t a permanent thing otherwise I’m gonna need to get two litter boxes in there

Yup he’s been desexed!
