My cat is very slow and not moving

Hi

Can anyone assist me with my cat health situation.
He is a 19 months old cat named Tyson.
For last 48 hours he’s been very slow/not moving as he used to.
He only eats when we give him food right front of him.
He drinks but not as much as he use to.
We have to Physically take him to his litter tray and then uses it.

Don’t know what to do !!!!!
I’m taking him to vets now n the morning but would be great full if I can get some advice at the meantime.

THANK YOU ALL SO MUCH
