Oh there are loads of gorgeous guinea pigs in rescues perhaps you could ring your local rescue? Petshops are very bad at sexing guinea pigs and would be nice to give a lovely one to an unwanted one

At you know they have had a health check ect.
I dont agree with breeding buns unless you are a serious breeder of a particular breed, there an estimated 33,000 rabbits in rescues, have a look at
Rabbit Rehome - Adopt an unwanted bunny from a rescue centre so many stunning bunnies young, old, big and small.
