I was carefulling watching that thread. There were a few ongoing discussions I was watching in it.
Not since people have posted a few pics of their cats, you closed it?
It had over 600 posts. People liked it. I cannot see what was harmed in leaving it be. Isn’t it the responsibility of the MODS to correct people if they stray off topic? Shouldn’t you be encouraging them to start another thread?
Maybe the thread itself had strayed a bit, but why close it?
