Yes some people are a little to quick to judge others.
Payitforward and I are in total agreement, we both come from countries where its considered rather cruel to have a completely indoor cat only, but unlike some others, i donot take that approach, i think whatever suits you and your cat, it all depends where you live etc.
I do however think keeping them in at night is a good idea, and i do that with mine.
But i would never say either are right or wrong, it appears some people think you are a bad kitty owner if you let your cat outside and this offends me.
Every ones circumstances are different and need to be taken into account.
