Sarah, thanks for the input.
I've had my oldest cat 12 years now, and am quite honestly a bit frustrated at HAVING to have a throw because the little blighters won't claw the things they are provided with!
They have:
1 large activity centre.
1 large scratchpost
1 slightly smaller scratchpost
1 wallmounted scratchpad
2 fairly large interactive scratch toys
I will say though,the catnip spray is a huge hit. I still found my youngest boy clawing the stairs earlier though.....stubborn little sod!
Out of the four of them, he's actually the main culprit for the stair scratching. Parsley, the cat we lost recently, always scratched either the hideous wallpaper(which we were OK about....because it's hideous!)or went outside. The older two are the main "sofa culprits" and the youngest one is just picking up everyones bad habits!
