That is a HUGE misconception: cats need to have a litter to live better lives. The fact that it is still around today is very upsetting.
Going through heat is not a fun thing for cats to go through. Mating is painful. Carrying a litter of up to 6 or more kittens is VERY rough on a cat. Birthing is also difficult, painful and things can go wrong and your cat can become ill or die. Caring for kittens drains every bit of energy and all moms nutrients. Kittens can become ill and die, and this is NOT uncommon. Its emotionally and physically hard for a cat to have kittens and than care for them.
Breeders know all this and prepare for it. Our cats are in top physical condition at all times. We know how to handle problems when they arise and most of us are hand raising sick kittens, or rushing someone to the vet for some reason. Its not an easy thing to do.
Yes, cats have been having babies on the street for years, blah blah blah, and that is why there are so many cats in shelters and being put to sleep everyday.
I personally think it is very irresponsible to let a DSH cat knowling have a litter. Accidents do happen, strays show up on door steps, but the responsible thing to do is SPAY your cat.
These kittens will be adorable, but will grow up and need homes. How can you be sure that you wil find excellent homes for them? We as breeders can never be 100% sure that our kittens go to wonderful ooving homes, but we do our best and send them along with contracts to protect them.
And what happens when these kittens grow up and arent altered? They have babies, and more kittens are out there that need homes.
Whats done is done, but if your cat is not pregnant PLEASE PLEASE PLEASE get her altered. It will be better for her, you and everyone.
