My guinea pigs seem to like it. They are more delicate piggies, but the inputs seem to me large enough and are well on two different pages, so one can always get out. Also at the processing so far I could not find anything negative. I would recommend it, it seems to me strong and a good size. For rabbits or thick Lugs it may be too low (from my feelings, can not test this, since we have no rabbits), but ideal for guinea pigs girls.
