I've been meaning to post this question for a while..but was only reminded today, since Franz is sunning himself in the bedroom window. I've never seen Franz "get excited" over the wildlife in my backyard--I'm on the first floor of a Brownstone, so it's a slightly elevated, perfect view. I have sparrows, mourning doves, pigeons and an occasionally blue jays and cardinals. Of course there are plently of squirrels as well. Yes, not only does A Tree Grow in Brooklyn, but wildlife as well! Franz looks out the window, but never chirps or trills over them. My two other cats from years ago, practically salivated over them. Do some cat just don't give a fig about birds/squirrels???????????
