You're right about getting on the floor with them. Our Stella gets snooty sometimes and runs away if I try to pet her, but if I get on my hands and knees and call her, she usually comes back and starts the headbutts and lets me in. My husband does the same thing and she really responds to him, begging, at times, for his attention. He has his routine with the two of them in the morning when he plays with them and gives them treats. It's their "special time". They are such wonderful creatures!
LOL, SO cute. I agree, they're amazing animals....truly little tigers in every sense of the word.
