attributes of cats undergoing the procedure. There are three surgical methods: scalpel blade, guillotine trimmers, and laser. No technique or method has been proven to eliminate the many complications associated with declawing. The International Society of Feline Medicine states that "Even if future improvements in surgical techniques can negate some of the adverse effects associated with declawing, iCatCare and ISFM believe this procedure is unethical other than if required to manage a medical condition and should be banned." Recovery, health and behavioral effects Onychectomy is an orthopedic surgery involving one (or more) separate phalangeal amputations, which requires general anesthesia and multi-modal pain management before, during, and after surgery. A 2018 study by Martell-Moran, et al found, in a study of 274 cats, that "declawing cats increases the risk of unwanted behaviors and may increase risk for developing back pain. Evidence of inadequate surgical technique was common in the study population. Among declawed cats, retained P3 fragments further increased the risk of developing back pain and adverse behaviors. The use of optimal surgical technique does not eliminate the risk of adverse behavior subsequent to onychectomy." The study found that inappropriate toileting, biting, aggression and overgrooming occurred significantly more often in the declawed cats than the non-declawed cats (roughly seven, four, three and three times more often, respectively, based on the calculated odds ratio). A declawed cat was also almost three times more likely to be diagnosed with back pain than a non-declawed cat (potentially due to shortening of the declawed limb and altered gait, and/or chronic pain at the site of the surgery causing compensatory weight shift to the pelvic limbs). In a survey of 276 cat owners, 34% reported post-surgical discomfort in their cats while 78% reported primarily tenderness. Recovery time took from three days to two weeks. Increased biting strength or frequency was reported in 4% of cats, but overall, 96% of owners were satisfied with the surgery. Some other studies found lameness after onychectomy lasting >3 days, >1 week, 8 days, > 12 days, 180 days, and 96 months. At one veterinary teaching hospital, between 50 and 80% of cats had one or more medical complications post-surgery; 19.8% developed complications after release. Other studies have reported medical post-op complication rates as 24% (Jankowski 1998), 53% (Martinez 1993), 1.4% (Pollari 1996), 82.5% for blade and 51.5% for shear technique (Tobias 1994), and 80% (Yeon 2001). Reported medical complications include:
