It is normal for all of my blankets and fleece to have lovely little decorative “holes” created by my rabbit designers.
Many times when rabbits find their special place to lie down, they will dig at it. I feel like sometimes this might be their attempt to create a “scrape” in their favorite spot. A scrape is dent in the ground that their wild cousins dig. It allows them to sit in the compfy spot but sit farther down in the ground a bit so that they are more out of site and feel safer.
So, what I do is get a very soft fleese blanket and build up the sides (either by putting old towels underneath) or if the blanket is large enough, then I will just use the extra material of the blanket. Though it’s not down farther, it gives that same feeling of being hidden by edges.
Placement of this is very important for Jack (and Rucy). If I were to put that in their hidey house, Jack would tear that thing up and push it out. But if it’s lying out in a larger space, then they just hang out on it. If it didn’t have the sides built up, there would be some “redesigning” go on.
I know for some bunnies, this won’t work, as some may have other digging intentions, or they don’t like the “scrape” you’ve made, but it might be worth a try.
Great bunny condo by the way!
