Yes, hot weather can affect a cat’s appetite, but this isn’t necessarily a problem! Research has shown that cats need less energy in warmer weather to maintain their body temperature, meaning they generally eat around 15% less food in summer. This is a natural way for cats to cope with the changing seasons, so there’s no need to encourage cats to eat more if this is the cause for their reduced appetite. Otherwise, encouraging them to eat can lead to your cat taking in more calories than they need. That being said, if appetite loss persists or you notice other signs of distress, consult a veterinarian.
