You know the way i look at it, those animals in pet stores need homes too, if everyone adopts from shelters, then they will be left, i am often so tempted when people are in the pet shop thinking of buying a kitten to tell them go to the shelter, because they cost a lot less for one and they are more responsible and give out spaying/neutering vouchers, which only one big pet store in my city does, the rest are so irresponsible and it angers me a lot,but then i look at the adorable kitten they are thinking of taking, and i keep quiet, it deserves a home just as much, not it's fault it comes from breeders or other irresponsible people who let their cats breed,anyhow that is my take on it. :) so don't feel bad.
As far as pet talk goes, it is simply THE BEST,there are no comparisons IMO,i have no need or desire to join any other pet forum on the net ever,here i am amongst true family and friends. :)
