While many people, especially newer members, may not be familiar with other members of The Cat Site given that we use board names and not our personal names, it is difficult to have no idea whether or not someone here is or is not a recognized cat "expert." In fact, Veterinarians, very experienced rescuers, geneticists, PhDs, teachers/University Professors of animal-related or population related topics, very recognized authors of cat behavior, health & other cat related books, and other Professionals in cat-specific or animal related fields are
members of The Cat Site and participate in its forums.
However, if anyone would like to read information and research about early age spay-neuter, the health and behavior of benefits of spaying and neutering, and/or the pet overpopulation problem by recognized institutions and known experts, feel free to click on any of the appropriate links provided in my signature line to take you to your area of interest. The facts are:
1) that it is safer and healthier for your pet to be spayed and neutered as early as possible.
2) that 7 weeks is a safe age at which to have your cat spayed or neutered (Winn Feline Foundation Study on Early Age Spay/Neuter
3) there is a serious pet overpopulation problem in most countries including the United States, and unless you are a knowledgable breeder breeding to protect specific genetic characteristics, it is simply irresponsible to let your cat produce a litter of kittens. There are plenty of animals available as companions or "mousers."
