Something that I figured out over the years is vertical scratching on something that stands out (couch, curtains other furniture), is that it’s often a sign of stress or boredom. Suki does it when she is bored or we haven’t played with her for a while. It’s a quiet ‘cry’ for attention in our house.
Vertical scratching can be seen as a sign of stress. But it’s an expectation when your cat has one or two specific places in the house, usually hidden or in quiet spots, where he keeps his claws in good ‘condition’ by scratching.
Becomes the scratching more common and on visible places or on objects that stand out — like a couch? That this is usually a sign of stress or restless (but also boredom — from my experience).
Does your cat have favorite scratching places?
