A cat broke into a greenhouse...guess why

[Catherine]

Edward doesn't react to catnip? 
That is unusual. Most cats react, some more than others.
He is missing out on something that makes a lot of cats happy.

I have seen cats lie on the floor and drool. They can barely walk. I have seen some get hyperactive.
Climbing into a greenhouse through the roof is a pretty extreme response. 
The cat really did look happy with the catnip.
