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. Needle depth, angle and technique depend on the point and on the size and condition of the cat. Note from the source chart: Avoid in pregnant cats. Commonly used in chronic kidney disease prescriptions.
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.
