As I type Onnie is scratching the heck out of the sofa Im sitting on. He likes to scratch those and the beds oh and the carpet runner for the stairs. Other than that
he's ok. I have many cat scratchers and tried endlessly to train him. I also always trim their nails to minimise their damage but lets face it our carpet runner looks like crap.
That being said Im not about to declaw my cat over a runner and a sofa. I dont know my stance if my house was being completely destroyed though- don't get me wrong I am against declawing and have steered away many other people from declawing but until ure in that position where its costing you thousands and thousands and the only other option is to rehome where more likely than not they will probably declaw the cat anyway I think its easy to say "I would never do that".
