Safety notes
Needling should only be done by a trained veterinary professional. Cats are small and sensitive, and shallow needling and short sessions are usual. This point lies along the back or hip region, close to deeper structures such as the kidneys, so needle depth is chosen with care in a small cat. Note from the source chart: Commonly used in feline chronic kidney disease.
Never apply pressure or heat to a painful area on a cat. If your cat suddenly cannot use the back legs, is breathing with an open mouth, or is straining to urinate, see a veterinarian immediately.
