No,you don't need a cat or dog. I have 2 black cats named Lilly and Loki that have their very own quilted cushions. But they are great company and Lilly lets me know when it is time for a petting break. When they want attention,they each wrap around my feet,so we stop work for a while and relax and hug each other.I personally think everyone should have a pet to relax with,but that's just my opinion.They don't want to get around the quilt I'm working. I turn the tv on the animal planet channel and they watch that all day while I work.It sounds crazy but they like it and keeps them busy.But I guess it sounds crazier that I turn on the tv for my cats,don't it?
