It might be the iron on fusible. I had a real mess once trying to FMQ over a Heat and Bond product. I thought it was the H & B light but it was regular H & B and I finally gave up. I did manage to use my buttonhole stitch along the edge because most of that is sewn off the applique. I stocked up on Wonder Under and I like that. Some people like Misty Fuse? There are a lot of different light fusibles on the market and you need to find one that your machine likes. I know that doesn't help with your kitty problem but someone else may give you some better ideas of what to do. Good luck!
