Well, if you needed them, here are two more very good reasons not to declaw cats. And this time it is not just anecdotal–scientific research has substantiated it…
Declawing Linked to Aggression in Cats
Declawing increases the risk of long-term or persistent pain, manifesting as unwanted behaviors such as inappropriate elimination (soiling/urinating outside of the litter box) and aggression/biting, new research concludes.
Declaw surgery (onychectomy) is illegal in many countries but is still a surprisingly common practice in some. It is performed electively to stop cats from damaging furniture, or as a means of avoiding scratches. Previous research has focused on short-term issues following surgery, such as lameness, chewing of toes and infection, but the long-term health effects of this procedure have not to date been investigated.
According to research published in the Journal of Feline Medicine and Surgery, declawing increases the risk of long-term or persistent pain, manifesting as unwanted behaviors such as inappropriate elimination (soiling/urinating outside of the litter box) and aggression/biting. This is not only detrimental to the cat (pain is a major welfare issue and these behaviors are common reasons for relinquishment of cats to shelters), but also has health implications for their human companions, as cat bites can be serious.
For the study, the author group, based in North America, investigated a total of 137 non-declawed cats and 137 declawed cats, of which 33 were declawed on all four feet. All 274 cats were physically examined for signs of pain and barbering (excessive licking or chewing of fur) and their medical history was reviewed for unwanted behaviors. They found that inappropriate toileting, biting, aggression and overgrooming occurred significantly more often in the declawed cats than the non-declawed cats (roughly 7, 4, 3 and 3 times more often, respectively, based on the calculated odds ratio). A declawed cat was also almost 3 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).
