I like this, it is really fantastic. The add on gives them more room to move around. Its like having an upstairs apartment for the small pets.

Pros: more room,

Cons: none

You can keep adding on. Great design and style. Your pet will love it.

Pros: It's like an apartment for a hamster or guinea pig

Cons: none

Used this for my hamster who loved it! It was a great addition that allowed her more room to roam. The only modifcation I did to it was add some cardboard on the flat platforms so that her paws didn't get stuck or sprained.

Pros: More room to roam, better exercising

Cons: none

Initially we just had our gerbils in the ten gallon tank. They went crazy when we added this high rise. They love to climb and scurry up and down the ramp. It really seems to add to the quality of their life.

Pros: Gives gerbils twice the room

Cons: none that I can think of

I Have this Setup For Jack My Hammy He loves to climb Up and Check things out. Accesories are easily attachible and it is well ventelated "Witch helps keep oder down" in my opinion one of the best cage options.

Pros: Gives Hammy More Room to play

Cons: Some Hammys Chew Bars
