First picture: dishes, grooming supplies, water bottles, toys, etc. Stuff on the left side were used for hamsters, right side were for guinea pigs and rats, but I suppose other animals might enjoy them too!
Second picture: pads and hay (bedding is sold).
Third picture: mesh bags for washing machine, fuzzy washing gloves, soft beds, and guinea-pig-sized t-shirts (jungle tunnel is sold).
Fourth picture: sturdy six-sided cage with two metal shelves. We had rats in this but it would also make a good home for a bunny or a bird. It could use a good cleaning. Measures 2' x 2' x 4'.
Fifth picture: enclosure used for guinea pigs. Each panel measures 2' x 2'.
