It is generally recommended to take your senior cat to the veterinarian at least once a year for a routine check-up and to keep up to date on vaccinations. Some veterinarians may recommend more frequent visits for senior cats or for cats with certain health conditions.
It is also important to take your cat to the veterinarian if they are showing any signs of illness, such as changes in appetite, weight, or behavior; vomiting; diarrhea; coughing; sneezing; or difficulty breathing.
It is always a good idea to consult with your veterinarian to determine the best schedule for check-ups and vaccinations for your individual cat. They will be able to take into account your cat’s age, health status, and lifestyle to come up with a plan that is right for your cat.
