Preventive care is the single most effective thing you can do for your cat's long-term health. A cat who sees the vet regularly, stays current on vaccines, and gets routine screenings will almost always live longer and have a better quality of life than one who only goes when something is wrong.
The timeline below is based on guidelines from the American Association of Feline Practitioners. Your vet may adjust recommendations based on your cat's individual health, lifestyle, and risk factors.
A few things worth knowing upfront
Indoor cats still need vaccines. Rabies is legally required in most states regardless of indoor status, and respiratory viruses can hitch a ride in on your clothes or through a window screen. Talk to your vet about which vaccines make sense for your cat's specific situation.
Dental disease is the most underaddressed health issue in cats. Studies suggest more than 70% of cats have some form of dental disease by age three. It causes pain, leads to tooth loss, and has been linked to heart and kidney problems. Annual dental exams and periodic cleanings matter more than most people realize.
The best thing you can do right now is establish a relationship with a vet you trust before you need one urgently. A vet who knows your cat's baseline is far better positioned to catch something early.
