Nowadays many households like to keep pets, and there are even some avid cat enthusiasts who enjoy playing with cats daily. Currently popular star Yi Yangqianxi is also particularly fond of cats; the cats he raises form quite a large family. So far, the domestication history of cats has lasted more than three thousand years, but cats have not yet been fully domesticated like dogs.

It is often heard that some people say they prefer dogs and claim cats are much more heartless than dogs. However, some others say: who says they are heartless? They are animals that can shed tears too. This dispute, who is right or wrong, should be proven by science.

Cats tearing up is not exactly like humans crying with emotion; they mostly tear up due to physiological reasons.

If a cat suddenly tears up, it is very likely caused by poor environmental quality, leading to foreign objects entering and causing irritation, which damages the cat’s eyes. Or the cat’s eyes might be infected by certain bacteria and viruses, resulting in redness, swelling, and bloodshot eyes, leading the cat’s eyes to automatically produce tears to keep the eyeball moist and protect the eye.

Another situation is that some cats have naturally ingrown eyelashes that irritate the eyes, which requires the pet owner to regularly pluck the eyelashes for the cat.

Sometimes inappropriate diet can also affect cats and cause tearing. Some owners think feeding cats meat every meal is the healthiest, but actually that is not the case. Too dry or too plain a diet can also impact their health, potentially causing internal heat and eye irritation. A healthy diet should be mainly light and include appropriate snacks, with each meal planned reasonably.

Therefore, for cats tearing up, the majority of cases might be because the cat is ill or not adapting well to its current living condition. When cats tear up, their physical condition should be considered first; it isn’t just about what you think it is. As a pet cat owner, I always try to clean the secretions from my cat’s eyes and spend as much time as possible with the cat. Giving plenty of care and understanding the cat’s habits and health issues is a must-learn lesson for every qualified pet owner.
