Spaying and neutering not only prevents unwanted litters of puppies or kittens but also keeps your animals healthier and happier! Animals that are not “fixed” go into heat, are more aggressive, and more likely to spray and mark. Male cat urine is far smellier! Female cats that are not spayed can suffer from uterine infections later in life. All of these are great reasons to sterilize your pets. If you can’t afford a vet, then take advantage of one of the many inexpensive local clinic options!
