(I can't link it from work - sorry guys.)
I don't think anyone would judge you for not liking the pet threads. Most of us are pet lovers, so I'm positive that as long as you're not out there hurting animals, everything's kosher. The only advice I have is the same advice the other girls give; if you don't like the animal talk, don't open the threads.
I love seeing everyone's pets (and kids for that matter). I have 2 puppies and it's nice to know I'm not the only one going insane trying to train them and putting up with their daily antics.
