Cats can be bathed before sterilization, and it is best to wash the cat a few days in advance, because it takes a week before bathing after sterilization. Generally, it is until the cat’s wound heals, the Elizabethan ring is removed, and the cat’s physical condition is fully restored. Afterwards, take a shower. The cat’s nails also need to be trimmed before neutering to avoid scratching the Elizabethan ring after the operation. It is also necessary to follow the doctor's instructions before the operation and thoroughly abstain from food and water to avoid the risk of suffocation caused by vomiting during anesthesia.
