MarionsQuilts-I can understand your perspective, but I don't share it. Nothing like this has ever happened when I have gifted a quilt (that I know of) but I think if it did, I would still feel the same. Once you gift the quilt your done....Since I don't know either of you (just playing devils advocate here) maybe in your sisters mind allowing her cats to use the quilts are the highest form of praise she can give to you. Either that or she is just astoundingly oblivious. Lots of people out there like that.
