Hello Alya
This cat needs a Vet URGENTLY right now!!! hes in critical condition and you cannot leave him suffering like this.
His stomach is probably full of urine if he hasn’t urinated….leave him much longer and his bladder will burst.
Take him to a Vet now…emergency.I’m sorry but you should not have pets if you are not prepared to give them the correct care. Its cruel to leave your cat in pain. VET NOW.
I’m confused, why did u bathe him in dishwashing liquid? Did he have fleas?
The dishwashing liquid will or has seriously dried out his skin. I would recommend taking him to a vet to get his skin examined especially if he has open sores.
Good Luck
