HEY @Pixiedust1234 !!! I hope this information is useful to you.
I have a 17 year old (female) cat who was struggling even to jump from the floor onto the couch, not even 2 feet, and she seemed to be struggling to walk some days. She would sometimes wince with pain. 😢 We took her to the vet after one and a half months or so of this happening, and she diagnosed her with arthritis.
She gave her yumove about eight weeks ago. And honestly, she's like a little bouncy spring lamb now. 🐑 She's jumping right onto the back of the couch now and right onto the dining table. 3 to 3 and a half feet in the air. And the other day she even jumped on top of the wheelie bin. (Nearly 4 feet up.) AND she jumped over our neighbour's 5 feet high fence yesterday. She has not done any of this for at least a year and a half to 2 years. She is whizzing around like she is half her age! The yumove started taking effect within 10-14 days! And no more wincing in pain
They are £31 a box, but there are 60 in each box, and you give them one a day, so it lasts 2 months, so it's worth 15 pound a month for your beautiful cat to not be in pain. 
It's easy to administer too. There's a little capsule full of powder that you open - and the powder falls out and you just tip it into the cat's food. It smells and tastes fishy. So it's useful to put it into food that is fishy (like salmon, tuna, herring, or white fish flavour cat food) - or actual tuna or salmon.
Makes sense to put anything fishy favoured in fishy flavour food. 
The best of luck to you, but I do recommend yumove ... My cat has got a new lease of life now. You can only get it from the vet though I think, so you may need to take your kitty in.
I notice some people are saying yumove is 'only a supplement' but so what? If it works, and it's improving your cat's health/helping her arthritis, stopping them wincing with pain, then surely it's worth a try?
(What's more, some injections for arthritis can have some pretty unpleasant side effects for your cat, including vomiting, loss of fur, and runny poo.) Probably makes them feel rough too!)
