Core vaccine requirements for kittens start when they are about six to eight weeks of age. Core vaccines include feline viral rhinotracheitis, calicivirus, and panleukopenia, also known as the upper respiratory vaccine or FVRCP vaccine. Additionally, rabies vaccines are given at 12 weeks and older, and the American Academy of Feline Practitioners recommends vaccinating kittens for leukemia at a young age as well.

Free-choice feeding is not recommended for most cats because they don't have the ability to determine how many calories they're getting over the day and over time will tend to gain weight. There's a study that shows if a cat eats just 10 extra kibbles in one day over a year, they will gain one pound of body weight. If you are free choice feeding, it's recommended to measure out their food. Half a cup for an adult cat is a good average to go by.

Human food will not necessarily make your cat overweight. However, the more human food your cat eats in addition to their regular diet, the more likely they will become over-nutritioned and overweight.

No, a cat is going to hunt because it's a natural behavior and an instinctual behavior for a cat. If they are outside, they will often hunt because it's fun and normal. They are not missing something out of their diet; they're just supplementing their diet with prey.

Prescription diets are recommended when there is a medical reason for it. It's not recommended for just the general healthy cat to have a prescription diet. A prescription diet is not necessarily more healthy for your cat; it's just been prescribed for a medical reason.

Wet food is not necessarily more or less nutritious than dry cat food; they just offer different nutrition. Canned food has a high amount of water content, but it can also be highly nutritious for your cat. Oftentimes, a canned-only diet is recommended for various medical issues.

No, cats should not be fed a vegetarian diet. In fact, if they are fed a vegetarian diet over a period of time, they will actually die. They are obligated to eat protein, as they are carnivores.

An elimination diet is recommended for cats experiencing gastrointestinal issues or skin problems. This diet involves feeding your cat a specific diet for a certain period, usually limiting the protein sources to one or using a hypoallergenic diet. By reducing the food ingredients to a select few, you can help manage your cat's health issues. If you have specific questions about harmful foods or proper cat nutrition, consult with your veterinarian or reach out to a pet hospital for guidance.

Switching your cat's diet abruptly could potentially cause gastrointestinal upset, such as vomiting or diarrhea. However, cats are generally more tolerant than dogs when it comes to changing their food. It's not uncommon for pet owners to feed their cats different types of canned food with various proteins, which cats can usually tolerate well.
