here's the plan soldiers:
Walk in and ignore the cats like they will you as you've been away a while and they're not so pleased with you
take off those boots! Heavy feet freak cats out
lay down on the sofa, floor, bed, and the cat will come to you...
Sit down at your computer and the cat will come to you..
Read the newspaper or a book and the cat will come to you..
Bring out their favorite almost forbidden food (if they are hungry or big eaters) and the cat will come to you or sit down with your own fragrant plate of food and the cat will come sniffing
Bring home a box with some crinkly paper inside and leave it out and the cat will come to the box..
