Be sure you have plenty of treats for your visitors to give your cats and even have some on hand for you to offer them.

I wouldn't like that either Gary, having someone coming by to drop in to "check on things" to make sure my kitties are well taken care of. Your vet comes by there and so does your friends from the animal welfare (don't they?) so WHAT IS THE %#&%@&^! PROBLEM!!!!!?? As long as they are HEALTHY, well FED, get vet care, have clean boxes to potty in and a warm place to sleep... Those people need to get a life!

Be kind to your guests, bore them to death with constant bragging about your wonderful kitties from the minute they walk in until they leave, in fact have them wait as they are leaving for you to tell them that one last cute L-O-N-G story that they just have to hear... I bet as a true PT'er pet owner, you have a rather large suppy of cat stories, enough to keep them there for hours.. I'd act all excited that I had a new audience to hear all about my WONDERFUL, BEAUTIFUL babies and be ready to tell the stories all day....

If they are dressed really nice, cover them with cat hair, handing them one cat after the other to pet..... They might not be so quick to come back if you keep them there for hours and send them off covered in cat hair.. In fact, even off them your cats favorite chair to sit in .. (cat hair on their butt, they'll never know!)
