Meet Speedy Gonzalez Roberts

Meet out new family member - Speedy Gonzalez Roberts. Someone dropped him off at our house - the louse. We fed him so he won't leave now. Brady LOVES him (or her - no one can decide what it is - guess we need to spay/neuter to prevent more cats!). I guess he can stay.....unless the owner comes by and picks him back up. How likely is that?
