I sincerely apologize for the delay in responding.
This is a case that requires an appointment with a vet.
Your cat's symptoms, particularly her inability to stand up, indicate that she requires immediate veterinary attention. This can be caused by a wide range of diseases – digestive/urogenital/nervous system diseases, poisoning, and so on - and only a veterinarian who examined her directly can determine the cause and prescribe the appropriate treatment. So please take her to the veterinary clinic as soon as possible.
Please do not hesitate to ask any further questions you may have. Thank you.

right now he is sleeping, but all he wants to do is lay down he can’t get up, when he does he’s tipping back and forth and then lays down.

My cat is shaking and seems to be moving in slow motion. help
