ive made heat pads too (rice works well also) add dried herbs like lavender for a nice aromatherapy pack too.
cats usually love fleece and warming pads.
i actually made a self heating pad with fleece and an old silver sun reflector (the ones for car windows), had the sun reflector, but it wouldnt stay put int he window and so was usless...
cut it nto cat sized pads (big ones though as i also yse them in the dogs crates so there about 24" x 18") then i took fleece scraps, made a quilt kind of thing to make it big enough sewed it to make a pocket big enough for the reflector to slide n and velcro on one end.
slide reflector in shiney side up towards whatever will sleep on it, and tada, self warming mats, as the cat sleeps on it it reflects the body heat right back up
the cats realy seem to love the fleece, or i put them under the dogs crate pads in the winter to add a little extra insulation/reflective heat.
or make a quit out of it, fleece is lovely for that.
fleace usually makes a good dust rag too everything sticks to it
