Adoreable. I've got a Tabby named Winslow II (after the 30 pound tabby Winslow-RIP), who looks just like snoopy!
I grow my own catnip, and buy it dried at the petco down the street, so my babies are very spoiled. I'd reccommend growing, I've got over 20 plants growing, and it seems as if it couldn't be easier. The cats know the difference too.
