It's important to understand that:
* Shooting a cat is cruel and inhumane. It is a form of animal abuse.
* Worms are a treatable condition. There are many safe and effective deworming medications available for cats.
* Shooting a cat won't solve the problem. It will only cause unnecessary suffering and death.
If you are concerned about your cat having worms, please consult a veterinarian immediately. They can diagnose the condition and provide the appropriate treatment.
