You can spray alcohol on your cat. Alcohol has a disinfecting effect. If your cat has a wound, you can spray a little alcohol on it to disinfect the local wound. However, it is recommended not to spray alcohol on a large area of the cat and to prevent the cat from licking it. 
Precautions for spraying alcohol on cats:
1. Before spraying alcohol, check the composition of the alcohol and do not use alcohol that is too irritating.
2. If the cat has a local wound, spray an appropriate amount onto the wound; do not spray too much.
3. It is best not to let cats lick alcohol, as alcohol is toxic to cats. If they lick a large amount of alcohol, they are likely to experience poisoning symptoms.
4. Note that alcohol does not kill external parasites, so do not use alcohol indiscriminately. You should carefully read the instructions.
5. Not all cats can be sprayed with alcohol. Do not spray alcohol on kittens or pregnant cats.
