Grisha the cat is ready for surgery! Thanks!

The cat Grisha used to live in a flat with his owners, but soon became unnecessary and was on the street. The cat fell ill with infectious diseases on the street. Volunteers took him to the clinic, where he was left for treatment in the hospital. Grisha overcame the infections, but now he has severe inflammation of his gums. The vet will schedule him for a tooth extraction operation, but he needs to be examined first. Let's help the stray cat Grisha to become healthy!
