Friendly Cat has started eating our catmint. Well the clue is in the name I suppose.
We used to have a visiting cat named (by me) "Friendly Cat", many years ago.
Over time, "Friendly Cat" became "Naughty Cat" on account of her tendency to leave unwanted deposits in my vegetable troughs.
My current cats love nibbling grass - as they're indoor, we make sure we have pots of "cat grass" in just about every room. My partner has a couple of fancy light-assisted growing things, and decided to put cat grass in them too. I think Goose likes it!
Neither of them are fussed about catnip, though.
