I am not sure if the term is actually afraid, but last night I got some catnip bubbles from Petsmart, and thought the kitties would both love it, but of course they were very curious, more hesitant about it..I blew them in the air thinking they would jump up and try to get them, but they just started walking backwards like the bubbles were gonna get them...after the bubble landed on the floor, they would paw at them, but they just didn't seem to care for them too much....any others like their catnip bubbles if you have ever tried them?
