Food aggression – what to check first?
Food aggression, also known as resource guarding, is more known in dogs, but can also occur in cats. The behavior in cats may show slightly differently, as dogs usually don’t jump on counters.
It is a behavior in which a cat displays offensive or defensive behavior around its food.
Here are some aspects to consider regarding food aggression in cats:
Calculate the Caloric Needs of your Cat
The first step in a food aggression case is to compare the cat's caloric needs with the amount of food it is fed. In many cases, there is room to move up the amount of food. Feeding guidelines are only guidelines. A cat's activity level plays a more important role than age. An active 10lbs outdoor adult cat easily needs 300kcal per day, whilst a sedentary 8 lbs senior cat may only need 180kcal per day.
Many feeding guidelines on bags are confusing, and I recommend weighing the food rather than relying on cup measurements.
Check the Feeding Schedule
The second step is to look at how often you feed your cat. Cats prefer to eat small meals often. Cats that are not being fed by humans eat between 8 and 12 mice per day. Each mouse is contributing about 30kcal to the daily intake.
Rule out Medical Issues
The third step is to rule out any underlying medical condition, like hyperthyroidism.
If you make sure you are feeding your cat enough food and spreading out the meals. Your veterinarian ruled out any underlying medical conditions. And still, the unwanted behavior does not decrease; we need to look deeper into the causes and treatment.
It's essential to understand why the cat is behaving that way.
Previous experience or upbringing may play a role?
In the wild, animals need to protect their food to ensure their survival. This instinct can still be present in domestic cats. If a cat showing food aggression behavior was coming from a situation where food was scarce, she may have experienced scarcity or competition for food in the past and, therefore, may be more prone to food aggression.
Feed Food Aggressive Cats Separately
If you notice any signs of food aggression in your home, please start feeding the cats in separate areas immediately. If the food aggression resolves with more food and more frequent feeding, and there is no underlying medical condition, it is time to seek help from a professional.
