Chynna didn't adopt me until she was about 1 year old but she loved catnip! Abby came to live with us when she was 4 months old and she hadn't had catnip before that, but she absolutely loved it once she got done sneezing, LOL
I don't give them catnip everyday because I don't want them to get so used to it that the playful effect wears off, so I give it to them once or twice a week.
Something funny happened with the catnip tonight. My cats only tolerate one another so when I give them treats I have to give them each a portion separate and away from each other otherwise Chynna will nose in and steal Abby's. Tonight I decided to give them some catnip and put some down on the corner of the rug for Abby and then on the other side of the rug I put some inside the track of one of those plastic circles that has a ball inside that they can bat around inside the circle (Chynna really likes that one).
As I was putting the catnip back into the fridge Abby was following me around so I decided to sprinkle a bit more for her on one of her real fur mice. Well, Chynna waddled up (she's a fat cat) and took over the mouse from Abby (Chynna never plays with the fur mice), so I sprinkled a bit more on a felt catnip mouse for Abby. Less than 10 minutes later I see Abby sitting on the rug looking at me with a less than pleased expression on her face
. I then noticed that Chynna had pushed the plastic circle toy to the spot on the rug where I had sprinkled the catnip for Abby, and gathered up the 2 mice and was laying on the rug so Abby couldn't get to her share of the catnip
