C&C Finally Done The Cage!!

So I finally finished my cage for my 3 piggies (Benson, Thor, and Jackson (if anyone get's the reference let me know)). It's a 2x3x2 level (plus storage underneath (so it's actually 2x3x3)) with a ramp on the exterior. I've had the top level for a while and just got the ramp finished so they have access to both levels. Benson, my older guy, doesn't seem to interested in the whole idea. Thor is for it and Jackson thinks it's the greatest thing since sliced....veggies.

They seem to really enjoy the large size of these cages. I have also gone with the polar fleece route. These pigs are super happy with their home. Benson has spent 2 year in an "old small cage" so the jump to the large one seems to be good. Benson also feels and looks better than before the big cage and 2 friends.

Is there anything else I should add or put into their cage for them?
