Before I started growing my own catnip in my back yarrd, I used to buy the big container. I'd split the catnip between two containers and store the toys in them. Then I'd take a toy out of the catnip for playtimes.

I also have a "toy box" and find I have to rotate the toys every 2 weeks or so. Nope, my 8 cats are NOT spoiled, not at all!

Different cats like different toys; and what one is using, they ALL want!

I think we have at least ne of everything at this point; I've owned cats for over 12 years and I only throw the toys out when worn out, not when the catnip scent is gone, as I replenish that.

Do you have a cat tree / climber? Set that in a window. They like to be in high places, and they LOVE to look outside! In the Autumn, set up a bird feeder out that window and keep it filled all winter.

Hope this gives you some thoughts!
