Basic tool kit for home-grooming long-haired cats. Believe me, you could buy a lot more, but this is enough to get you started.
Clear plastic Elizabethan snap-on collar in a small-enough size for your cat. (Ask your local feline veterinarian if they can sell you one. Costs about $10. Make sure it is a SNAP-ON collar, not a collar with velcro. The sound of the velcro scares some cats.)
