I have to hang stuff on the sides of the sofa to stop Selma (my cat)
from sharpen her claws on my sofa or fine chair.
(the chair - the blue one you see a the bottom left of the picture)
well, it isn't pretty, but neither is the result of her scratching.
This is how my funiture looks after my very annoying cat has been by.
And I do have a scratching tree she can use, but she only uses it when I am in the room.
very sneaky of her.
