hi my cats had kittens almost 4 weeks ago, im quite lucky as ive managed to find homes for all three litters, alomost all of the kittens will be staying on the same street though as they are going to my friends who are close neighbours. All the kittens are related as the mums are sisters.And im a bit worried that as they get older the kittens will end up getting each other pregnant.which although im no expert, im assuming isnt a good idea. So Ive told my friends that when the kittens are old enough i will pay half the cost of having them speyed/neutered seeing as they are helping me out by giving the kittens loving permenant homes. My OH thinks this is silly seeing as im not charging anything for the kittens, what should i do?? i took on my 3 cats when they were pregnant and its been hard work and scary at times. i know that once the kittens leave they will no longer be my responsibility but i do still feel slightly responsible for their welfare.And by offering to pay half towards the cost of speying/neutering it will ensure that they are all done at the earliest opportunity and it will save the babies having babies while they are too young.
