Kittens should be vaccinated every 3-4 weeks from age 6-16 weeks. Then they should be boostered at 1 year old, and then every 3 years after that. Rabies vaccination is also recommended, so you should contact your vet on how frequently is should be done based on the region you live in.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! At 4 months old they only need two FVRCP vaccines. I recommend giving the 2nd one 3-4 weeks after the first. If you want to do the 5 in 1 vaccine for cats then you should give 2 of those 3-4 weeks apart. It won't hurt to change to that kind. I hope this helps!

Nancy should be dewormed about every 6 months. Another option is to use a product such as Revolution which will protect her against fleas and has activity against intestinal worms (although it will not be as effective if she is coming in contact with large amounts). Kittens start vaccines between 7-8 weeks of age and get vaccines every 3 weeks until they are 16weeks old. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.

It is important to booster vaccines in kittens every 3-4 weeks until they reach 16 weeks of age. The reason for this is because they are slowly losing protection from the antibodies from their mother, and they will not have a full response to the vaccines until those are completely lost. Giving a kitten vaccines every 3-4 weeks keeps them protected during their kittenhood. I have attached a link to the vaccine recommendations from the American Association of Feline Practitioners for you to review if you would like additional infomation. https://www.catvets.com/guidelines/practice-guidelines/feline-vaccination Please let me know if that was helpful. Thanks for using PetCoach.

what are all the vaccines the cat must have and what age should they be given?
