Nice touch, but mine would chew them off in no time at all. We tried something similar a number of years back but they wouldn’t have any of it.
I would think one would need a good supply of bandages trying to get them on most cats
Cats who have never been outside are sometimes scared of it. They do not need to be outside.
I had a cat whose personality totally changed after being neutered. He was still a great cat, but just a different cat. Depending on the cat, they can feel trauma after any procedure. What does a cat understand about any operation or medical procedure?
The cat who changed was very affectionate and hated the outdoors before being neutered. Afterwards he was king outdoor hunter and much less affectionate. He was not declawed. He died by being struck by a car. He would have been better off declawed and indoors.
