THESE are the emails I like to get -- !! Alda is obviously a responsible owner, researching options before jumping in, and when she does so, doing it great -- and also, kudos to your pit bull, Alda -- the media needs to focus on these stories, too, instead of the typical killer-pitbull type stories!
As a further note, though these two loves are peas in a pod, and are obviously getting along great, they still need responsible ownership. This means when they're not supervised, they're separated -- it's that simple. That should mean the pup being crated separately from the cat.
Also, during play, the pup and the cat should be closely supervised -- while dogs are smart, they're not always able to differentiate between their prey-drive instincts. So while these two might play together on the bed GREAT, when the cat runs away, etc., the pup's prey-drive might kick-in, over-riding the 'play' mode and instead turning in to a hunt --
-- of course, this is a worst-case scenario, but it's better to approach this from a preventative measure --
GREAT WORK, ALDA!
