Ugh my cat just had surgery this morning

So my kitty just had his surgery this morning around 7:30am I picked up up at 1:30 today he was still severely drugged up still because he had just woken up when I got there anywho just a little bit ago he got up and he was soaked and he had peed on himself I tried whipping him off with whiles but he kept hissing at me I don’t want to hurt him and I’m scared he got the Incision wet from him Peeing all over himself is he going to be okay he won’t even let me see it he keeps locking up his legs
