I have accidentially stepped on my cats tails or feet before, and they yelp out and I always feel so bad...they go running like I did it on purpose, but I just bend down to their level and tell them I am sorry..this will work with Rocky and Fluff, but Ash hasn't completely gained 100 % trust with me yet.....I just wonder if they really know I didn't mean to step on them..I hope so!
