I am putting up a cat climbing wall with shelves, (with help from my eye rolling father). But I am not sure how far apart to put the shelves to give the cats enough of a challenge to jump up, without being too high. One of my cats is quite athletic but the other is not quite as brave.
I was thinking of stepping them up at vertical intervals of about 25 cm (not quite a foot) but maybe that will make it a bit boring and they should be further apart.
Any thoughts anyone?
Thanks
