Three of mine are declawed, and go outside. I’ve had two of them for 7+ years, one for 3 years. So far, the only difference I can tell between them and the one with claws is that they don’t shred my furniture. They catch birds, mice and rats just fine. We do have a place under the front porch that they can get into but bigger animals cannot, so if they encounter a dog, they have a haven.
