Less fighting means less pain for the pet, less expense for the owner. Unneutered household pets are usually anxious and frustrated. Dogs may show this by whining or being overly aggressive. Female cats will caterwaul while male cats will spray, marking off their territory in or outside the house by depositing a pungent smelling urine. Pets spayed or neutered before nine months of age will probably never develop these behaviors, but even older animals benefit from the operation.
Neutered pets are calm, content and comfortable in their home environment.
And When The most common surgery performed today by veterinarians is the spaying of females and the neutering of males. Under proper veterinary care, there is very little risk. The animal is usually up and about within one or two days. The cost of the operation varies greatly, depending on the size of the pet, its health and the veterinarian. Females can be spayed at six months, before their first estrus cycle.
