LOL, it sound like if your Cat was human he would be a great candidate for that new show on one of the health channels called "My Strange Addicition", LOL. That is so weird that he has a preference.
Here's an idea for a good Youtube video ;) serve him up a plate of catnip and a plate of a piece of warm and natural batting and if he ignores that Catnip over the warm and natural batting, then you know he is unique, LOL. Disclaimer: (I realize some cats aren't affected by Catnip and it's just mean't to be joke, not cruel in any way ;))
Explosive blessings, abundance and inspiration to you all!
