I will 100% advise against it,
Not once you mentioned the life of the cat in your OP. you just mentioned that they will stay indoors all the time. But what about the cat? how active will this cat's lifel be even if he/she will stay indoors all time? how big is the space for this cat? Would the cat have enough room to run at full speed? is their stairwell, she/he can dart off and run up and down? can the cat have "safe" place to hide (where no human can reach her.him) in this house, if she is threatened by visitors, loud noises etc.
Trust me when I say this: Cats will constantly remind themselves their entire life that their claws are missing every time they have the urge to act like...well.. a cat! jumping, pouncing, swatting etc.
Imagine that you are cat, you can leap vertically to great heights, well technically you should be able to, but guess what...you got no claws to jump and hold on to what you need to hold on to get to places...
I have a luxury to live in a home with a fairly sized yard (backyard). My (front paws declawed) cat is semi-indoors cat, she loves to go and play in the yard, chase rabbits, birds, mice etc. clean her teeth with grass, lie in the shade of thick bushes, like she was some tiger in the jungle...Cats love the outdoors, cat's are not the most docile and domestic pets, they carry the genes of their bigger, wild, feline counterparts, they need space to run, jump, claw, stalk/hunt prey and exercise... Having said this, my cat really never saw the outdoors the first two years of her life, she had to understand that she can't just wonder off, and thankfully so far (almost six years) she doesn't wonder off too far from the house and is always near by.
I mean I kind of get why people with small apartments want cats, but at the end of the day, having a declawed cat cooped up in a tiny apartment with very few windows all the time will not give that cat the happiest or even an ideal life. depends how good of an owner you are, and what breed the cat is,m but chances are that cat will be miserable and overweight/obese in no time and have health issues about 4-5 years into her/his life. It's perfectly fine to have cats indoors all the time, but those cats still need space to run, jump climb stairs, scratching posts etc. and have a happy and active life.
Even if indoor cats live a "longer" life, the question is how healthy and happy those cats live the last 3-4 years of their life indoors before dying?
Most old/dying indoors cats I've encountered have been cats that suffer from serious heath issues, severe pain and suffering, immobility, blindness and cost their owners crazy amount of vet bills.
There really is no shame in a cat dying out in the wild 3-4 years earlier than his/her "time" by the hands of some wild animal (Raccoon, dog, weasel, Opossum etc.) because that is their nature, they are indeed wild creatures that hunt or be hunted. ( I had a cat that was killed by an opossum) They probably wouldn't want it any other way: granted they still have their claws to at least defend themselves and fight to their (inevitable) death with that said wild animal.
