Read the heartbreaking accounts of the abuse of children being abused and you might start to think about neutering and spaying them, instead.
Great Britain is a small densely, some would say over populated island. Never mind adding to the mix of feral dogs, cats and children.
I knew children that picked up their pet cat by the tail, whirled him around and then let go. Lovely.
Letting your cat 'have just one litter' could be exposing her kittens to that sort of abuse.
The family lived in the next road, the father self-employed, the little brother 3 years younger, and we were forced to have him playing with us at weekends, where he was allowed to insist we played cricket in the back garden all Saturday afternoon.
We once ran like mad down the entry, and in through the front door, slamming it behind us as he was chasing us wielding a full size cricket bat. The front door had 2 vertical reeded glass panels which he smashed in temper. The irate mother whacked my friend on the leg with the bat. I was just terrified she'd start on me.
He was about 8, and the 'prince' of the family.
I imagine the cat wished the boy had been neutered to calm him down, and his sister to stop animal cruelty.
Do you really want your cat's future kittens to go to a life like that?
Having a kitten in a home is like adding another baby into the mix, and the outcome cannot be predicted.
I imagine in the story above, the cat was about 4, the girl had pestered for a pet, and the pet pushed back when her little brother was born, finally arriving when he was 4 and able to 'treat it properly'.
Except he didn't, and neither did his sister.
Please unless you are going to keep all the kittens, and as house cats and turn your house into a fortress, don't. A queen can have a litter of say, 6 kittens, with 1, 2 or even 3 fathers, after multiple matings while on heat.
We were forced to take a kitten by a scheming dd and friend. The owner forgot to give its mother the pill. Rural France. The father was a feral tom, and the 3 kittens, all male the result of appalling inbreeding. Their half-brother also their uncle. They all had long front paws and could open doors. He was neutered. He hid behind a door to try and put his claws in our elderly Maine Coon's eye. He left. He was just 7 weeks old when he was dumped on us. Going to be drowned. Apparently. She never recovered her confidence.
That sort of inbred cat could father your cat's kittens.
