I have had three declawed cats, the choice to declaw each of them was not my own but nevertheless... the oldest two are 17 and 16 and none of them have ever had any physical or behavioral issues. Never once in 17 years of owning a cat have we had a cat go to the bathroom outside the litterbox, not one time ever. Never had the cat peeing in clothes, never had them going on carpet, furniture, anything. The 17 year old is just now starting to show signs of "old age" in the form of decreased kidney function which is leading to increase urination and yet she still never forgets where she is supposed to go to the bathroom. These cats have been ACCIDENTALLY without a litterbox for up to 24 hours and they have never ever gone outside the litterbox still. My point is I look at firsthand knowledge not what other people tell me... cats can live long, happy, normal lives after being declawed. I think you hit the nail on the head Tessa, if it is the choice between giving the cat a good home or not having one declawing is an option that should be on the table. The amount of cats and kittens in shelters and being PTS outweighs that of dogs... there are just so many of them. If someone is willing to take one of those cats in and provide a good life for it, declawing is WAY WAY more humane than death.
