Reproduction. Voles can breed during any time of the year, but spring and summer are the most common seasons for breeding. A female vole will have 1-5 litters per year, each litter averaging about 3-6 babies. Females are able to reproduce at about 1-1 Â½ months old.
There are so many cats without homes that some shelters neuter kittens early, at 8 â 12 weeks old, so they are neutered prior to adoption. This is the only way they can guarantee that a kitten will be neutered. Normally, cats are neutered at 6 â 8 months old.
  Cats can be neutered as early as when they first reach 2 pounds. It's recommended to wait until they are at least 3 months old. 4-5 months is the best age.hey have to be at least 8 weeks old to be spayed or neutered. It doesn't have to be done so early, but it should be done sooner rather than later, as studies have shown that â¦ cats that are spayed/neutered later are at greater risk for certain serious conditions and diseases, such as breast cancer.
