Bald eagles do not live in groups but only in a pair. they will stay together and if the female were to die the male will not breed with another female.
There is also a risk of complications, including infections and bleeding, and a possibility that the nail will grow back. When using the Resco clipper method, the cost of declawing a cat can be anywhere from $40 to $300. The surgery is fast and easy, so it typically tends towards the low end of the spectrum.
Cats are declawed by a veterinarian cutting off the last joint of the toes on their front feet (and sometimes back feet). This removes the entire claw structure, the tendon and muscle that extends and retracts the claw, and severs the nerves running to the claw. It is extremely painful, and is painful for days after the operation. I have no idea how much it costs in terms of money; in terms of psychological and physiological damage to the cat, the cost is immense. Please DO NOT DECLAW YOUR CATS. If your furniture is more important than your cat, don't get a cat.
