That is such a sweet picture!
I wish our cats would just accept Beckham, it's been 6 months and they still hate him just as much if not more! He will just walk by and the little female will come flying out of nowhere and attack, the big chubby male will just throw a fit. Hissing, spitting and growling, which of course causes Beckham to start barking (very annoying). I don't know how to help the 3 of them get along, I've tried treats, etc...but our cats won't get over it. I'd love suggestions too.
