Kittens always need two sets of vaccinations at about 9 and 12 weeks old. These vaccinations are vital to protect them against diseases that can be caught from other cats and your kitten must have them before going outside.
The vaccinations need time to be fully effective, so I recommend that kittens can go outside from four months old. However, this should be in a secure garden and under the owner’s careful supervision.
It is also now law that any new kitten owner has their pet microchipped. Most cats can be microchipped from the age of 10-12 weeks. and must be chipped by 20 weeks.
Keep in mind that kittens can get pregnant from only four months old so, if your pet is likely to come into contact with other cats, you should consider having your pet spayed.
