A kitten arrived under our car a week before Christmas in out townhouse. No one wanted her, so we coaxed her out and she ate 3 adult size food portions before returning under the car. We left our garage door open a little each night so she could have somewhere warm to sleep. After 9 days she finally let us touch her. Our own Burmese died 2 weeks later not long after we discovered Ruby was actually Ruben.
Today we took on an 8 year old Labrador that has never had any love in his life, his tail has not stopped wagging. His owner would not even bother to fill his water bowl regularly.
