I am about to buy a puppy and a kitten and I am not sure whether I should get them neutered/spayed straight away. I have read conflicting reports from different vets as to which is the best way to go. I will be buying a male puppy and female kitten. I definitely do not want them to have puppies and kittens in the future.

On the one hand they say your should let them go until 12 months and others are saying 6 months at the latest. I really want to do what is best for them. Any help would be great.

Usually it is easier to neuter / spay if the animal is fully grown, so the organs are easier to find (cos they're bigger) and there is less chance of the vet damaging something else. There is no need to wait until they are a year old though. Consult your vet.

If you are looking for a vet, have a look at the category Vets & Veterinary Services on this site. You'll find many listed there.
