WElcome to the board Allie! I had the same issue with my dogs/cats, the Humane Society had a 10 yr old cat that no one would take and I told then I couldn't coz I was already maxed out: they begged me to take her and told me to just "hedge" the # of animals I had so they could let her go home with me! There sure do seem to be quite a few of us here with copious amounts of bikes, dogs, cats, and horses!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
