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 not long ago.
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. 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 meowing 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 probably thinking "MOM!!!" . I 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
They both really like catnip. Chynna rolls around in it but doesn't eat much if any of it. Abby loves to eat some and roll around in it too, but she likes me to be with her when she has catnip because she wants back and tummy rubs.
