" I think its cruel to keep a cat indoors all its life."

An indoor cat lives longer... costs MUCH less at the vet... and if provided with good 'entertainment' will be JUST as 'content' (if not more so) than a cat that goes outdoors...

"cats should be de-clawed"
My indoor cats are declawed... that way my $100 cat isn't wrecking my $700 sofa.... or my $900 carpet... or... or... or...   

They also don't get yelled at for doing what comes naturally.... They also don't even know they've been declawed...   Their brain isn't much bigger than the end of my thumb...
