Two male guinea pigs

Handled frequently, very sweet. I took them in from pet smart because they have head tilts and were unable to be sold. (They were there for five to six months) I have two kids with a third on the way and dont have the energy or recourses to keep up with them. I paid $200 for supplies. Only asking $40 to make sure they go to a good home, and will not be rehomed again. The head tilts do not effect the health or mobility of the guinea pigs and they have been vetted to attempt to treat it.
