The are 4 male ratties available for adoption at Toronto Lawrence square petsmart. The solo male rat is a bitter and needs to stay solo. The 3 paired are still biters but not as bad. If anyone can help please do. They are super adorable!!! edit I adopted the rat on it's own and my friend is taking care of the rat. The other three still need a forever home. Please contact the pet shop and speak with the manager Tyler if you can help give the other three a home. They all go together so you will need to take all three.
