I just rearranged Stinker’s pen. Not much, just put his food and water bowls (they’re attached) into the litter pan with hay on the side and of course the place to wee and poo. I moved the pan to the area he seems to go a lot other then when he was eating before. I also angled his carrier a little bit, as when I first got him I had no pen so I just boxed him into a corner of the room. His litter pan was right in front of his carrier he sleeps in..with the door open of course. All he has done is hop around and around and inspect everything now. LOL
In and out of his carrier. In and out of the litter box. I gave him a new bag with some tissue paper inside yesterday and as you can see below, my cat decided she enjoys it more than he does. LOL However, he does like crinkling the tissue paper.

This is the bag. It’s an old Christmas gift ag. It’s kind of dark but that thing stinking out is my Sophie’s tail sticking out. Stinker is just off to your left wondering what the heck she’s doing! LOL

This is the way the pen is now. All I did was move the litter box pretty much from where the white blanket is there in front, over to where it is now by the bag and angled the carrier where it was looking straight on before.

Just a couple of pictures now of Stinker Bunny nom nom’ing on his veggies.
I may be prejudiced but he is SO CUTE!!

2 weeks post neuter. He’s getting better at controlling his piles and urinating only in the cage usually, just not always in the box
he’s working on it! Proud of him
