Some shelters / states will not let you take the kitten if you are going to declaw they are against it. I would get a spray bottle with water it is a great deterant. there have some apple bitters at the pet store that cats do not like you can put on your furniture if she is scratching they have some great cardboard scratchers that are rectangular shaped and work really well. I have had many cats over the years and I may not be an expert but these are the tricks we used and work.
