That too makes me so mad when people do that. It is their responsibility to take of them and to not up and take off on them. You are very right Mary, they should be tied up just like those dogs and left for days without anything.
You should try to find out who the landlord is and if you can get a forwarding address and tell them off. Their mail will def have to be forwarded to them somehow.
We should ALL petition to make this a new law that makes this act illegal. What would we call it??
