It is produced from hot pepper sauce. It is used by spraying on or around the operation area. When the patient wants to lick the wound, it gives up licking the wound due to the bitter taste. However, spray-induced burning causes the patient to scratch the area with its paws insistently and to rub against the environment. In addition to them, the bitter spray sprayed on the wound irritates the wound and delays recovery. It may cause permanent lesions on the wounded area. It is not a highly preferred method.
