I've made appointments to have the first installment done at the vets. I thought about it, and if I don't like the results or the cats hate them, I don't want to have a bunch of kits laying around that are only partly used. Also, that way I can have the vet try a couple sizes and see what fits best. I will let you all know how it goes. Bassett goes in Wednesday, and Tilly and Nutmeg go in on Friday
