If your cat doesn’t receive sufficient vitamins and minerals this can make them more likely to have behavioral difficulties. You should make sure your cat is on a complete and balanced diet. Additionally, it’s not just what you feed your cat- it’s how you feed them. Puzzle feeders are an important way to encourage cats to get the exercise and mental stimulation they need to be happy. Puzzle feeders don't have to be expensive; you can make something cheap yourself from common household materials, or buy a treat-dispenser ball.
