A well balanced diet is a must for cats. They have very specific nutritional requirements which if not met, can be life threatening. There are many premium brands of cat food on the market which cater to a wide range of needs for kittens, pregnant and nursing cats, active cats, senior cats, obese cats etc. Your veterinarian is the best person to speak to in regards to the best cat food for your cat.
It should also be noted that raw chicken necks or chunks of raw beef should be provided to your cat twice a week can help maintain good dental health. Unhealthy teeth and gums have a greater impact on the body than just causing bad breath, pain, and infection. As the gums have a rich blood supply, bacteria is readily transported to other organs (such as the liver, kidneys etc.) in the body causing damage and even organ failure.
Even if your cat isn't sick, an annual vet check is important. Your vet will thoroughly check your cat for signs of sickness and aging related disease and can answer any questions you have.
There is much debate as to the frequency of vaccinations. Your vet is the best person to speak to about how often he feels your cat should be vaccinated. This would depend on your individual circumstances and location. For example, some countries require an annual rabies vaccination.
Monthly health checks at home:
Catching possible health problems early is an important aspect of cat care. It is a good idea for cat owners to give their cat a monthly check at home to ensure everything is going well. This should never replace professional examinations by your veterinarian, but as most pet owners only see their vet every 6 to 12 months, it is advisable to keep an eye on things between visits so if you do notice a change you can seek veterinary care immediately.
