How do you get your cat to stop scratching the carpet or
furniture? I have a no scratch spray which gives off a terrible
smell for the cat, however when I spray where she scratches
she finds another area to scratch on the carpet... I have
been to a vet for a checkup and they trimmed her nails which
reduces the damage. Btw I do have two scratching posts,
one is a vertical scratching post and another is a horizontal.
I also keep my cat at the back of the house away from my bird.

How do you get a cat to like being groomed? I adopted
my cat recently (2 months ago) and I soon found out that
she wasn't pleased of the idea of being groomed. I praised
her vocally saying, "You're such a good girl" in a high pitched
tone but it wasn't good enough. She'd run away after a
minute. I can't get in the areas on her stomach, top legs, the
hindquarters, inside her legs or on her tail. There's a huge matt
but my parents won't take her to a groomer to get it out... I've
tried giving her treats but she doesn't like them, I sat 2 treats
near her food bowl for 24 hours but nothing. I suggested buying
a different packet of treats or even cooked chicken but my
mother refuses to "waste money" or "any of my time for nothing."
What should I do?

How do you stop a cat from doing her "business" outside
her litter box? Alright, it's stupid but she goes in the litter box
but her hindquarters are outside the litterbox... Do you know
where I'm going here? I've suggested a hood over the litter box
but my parents think it's somewhat ugly, there for she keeps
doing it.

How much exercise does a cat need a day? She's 3 years old
(turning 4 in dec) and at a normal weight.
Thank you so much if you answer these questions. It's putting
a lot of stress onto me and my parents for some of these
unanswered questions.

(ps - I see that you have some beautiful art in your signature, but no credit towards who made it. It's a really disrespectful thing towards artists, so please at least put a "art by ..." next to it)
You should really invest into getting treats that she likes. That could work towards solving many of these problems.
Basically, when she does something good - reward her with a treat. If she scratches at the correct place, give her a treat. Over time she will establish that treat = good = shes doing something right. I've also seen some colorful things that people glue onto their cats nails, which apparently stops them from scratching, but I can't speak there from experience.
The same thing goes for grooming. Start out with petting her while giving her treats. After a couple sessions of that, start touching places where she doesn't like being touched, legs, belly, etc, and keep giving her treats. When she seems to be used to that, get a wide tooth comb and gently touch her with it while giving her treats. And eventually you can move up to actual pet brushes. The important thing here is consistency and being persistent. Some cats just don't like being brushed, but giving her treats can help keep her around for long enough to brush out as much as is needed.
If your parents don't want to get a hood (do they prefer poop on the floor over a hood on a box??), then try getting a bigger box. Maybe she thinks she doesn't have enough space in it. A higher one could help too.
Don't think there's a set time for exercise for cats, it largely depends on their personality and how much they eat. If your cat eats a lot and isn't very active on her own, then spend maybe like, an hour every day playing with her, broken down throughout the day? Like 15 minutes in the morning, 30 minutes during the day, 15 minutes in the evening. If she's anything like my cat, who barely eats anything and is still an unstoppable ball of energy, then she probably doesn't need additional exercise. Doesn't mean you still can't play with her~
