Aly I don't think she was inferring your indoor cats were miserable, well it was not her intention I believe.
This debate has gone on and on before, and everyone knows where everyone stands on it I think.
Everyone is entitled to make the choices that they think is right and suits their circumstances for their pets.
I personally have no problem with indoor cats only, and I don't judge anyone, whats right for you is right for you.
cheers.
