help

this might seem a bit out of place, but i need help.
is anyone here a vet?
my cat's been behaving oddly since sunday, and yesterday night he started to throw up. there was no blood, just the food he had eaten previously that day. there's no signs of fighting.
by behaving oddly i mean he tries to pee but he cannot, and now he's lying down on his carpet. he's been drinking water, but no eating.
im taking him to the vet soon, but i'd still appreciate if any of you could help me.
