It is a wise decision to spay or neuter your pet regardless of whether or not you intend to have your animal in the house or outdoors. Did you know that a lot of behavioral issues arise from pets who are not spayed or neutered? If you’ve ever had a cat decide to mark its territory in your home, you’ve experienced a possible reason for that mishap. Even if the cat was fixed, he or she could have been spayed or neutered at a much later date than is recommended for felines.
