I put my spoiled brat on too he is full grown weighs 2 1/2 lbs. Ive run over his foot a couple of times scares me to death he screams so loud then I cry cuz i hurt him Ive killed two kittens and a bird since I've been in a power chair makes me a nerves wreck when my animals are around my feet they get on my foot pedal but still. I usually pick him up and carry him.
