Saw two kitties at Petco this afternoon (bonded brothers - 5 months old) that could be related to your little "quilt tester". Our quilt tester died several years ago at the ripe age of 18 years! My Lhasa (may she rest in peace too) used to rearrange my blocks if she got into the room where I sew - I don't have a design wall so I would use the floor - I would have to put up a child gate to keep her out while I put them together from the floor - she would sit on the other side and complain! She also used to sit on the quilt while I sewed the bindings on - I miss her!
