Only occasionally do any of my guinea pigs go inside this hidey. They do enjoy sitting on top of it.
However, as a pig transport method, I've found it essential. Since this roomy fleece cozy arrived I have never had to catch a pig with my hands. With it I can easily and safely catch all four pigs in a couple of minutes to move them to a playpen. It's also a handy way to keep them on the scale while I weigh them.
Often they will run into the pocket of their own accord. If not, I just give them a nudge or scoop them up. It is much less stressful for them than being grabbed. Unlike a basket or bin, I can hold the top shut to prevent jumps and it is easy to maneuver inside a C&C cage.
It is also provides a nice way to hold a shy pig on your lap.
Everyone with pigs should probably have one or two of these, particularly if their little buddies are kept up on a table and need a secure ride down to the floor.
