I don't have any declaws but since I do have the little ones with razor sharp claws I'm going to post anyway!
I trimmed the babies nails recently and boy it sure does help! It doesn't stop the climbing or playing but it prevents the needle like OWIE!!
I use regular fingernail clippers and just take off the very sharp tips of their nails. I don't think you are going to have any problems with the furbies as long as you keep those front claws trimmed.

Just wanted to say...I'm covered in scratches and having a ball!!!
