Hi Jenn, I’m not sure if the photo is still loading, but I don’t see it yet.
My bunnies like to rip at rugs and carpets and towels – they will put some holes in it, but you can see the sections they pulled out separate on the floor – so I knew they haven’t eat in it.
Do you see pieces separate from the whole rug? (as in he just dug and tore at it, but didn’t eat it)
Also, are you sure there has been NO poop for 8 hours? If so, than yes, I would be worried he had a blockage and should see a bunny savy vet (as there insides aren’t like cats and dogs, which I’m sure you know)
What I do if I’m worried that they may not be pooping is completely clean out their litter box and the surrounding area if he’s not 100% litter box trained and see from there if there is no poop.
I’m glad that he’s eating hay and acting normal, is he drinking?
Not pooping for a full 8 hours while still eating isn’t good though, as the poop needs to be going somewhere.
