11 Fun and Fascinating Facts About Pet Rats

Rats make for one of the most rewarding small pets to own, as they are highly intelligent, interesting little animals that often bond strongly with their owners, and make for excellent companions that are rather more low maintenance than cats or dogs.

Whether you’re considering getting a pet rat for yourself or your child or already keep one or more of these lovely little rodents, this article will cover some fun and interesting facts about pet rats that you might not already know! Read on to learn more.

1. Rats Laugh and Show Happiness

Rats express their happiness through high-pitched squeaks which can be considered their version of laughter. When playing or interacting, you may hear these delightful sounds. The pinker their ears, the happier the rat generally is, signalling good wellbeing and contentment.

2. Teeth That Never Stop Growing

Rats’ teeth grow continuously throughout their lives and they must gnaw on toys or suitable objects to keep them at a healthy length. Grinding their teeth is usually a sign of contentment and relaxation, but can also be an attempt to soothe themselves if they’re upset or stressed.

3. Poor Eyesight but Sharp Senses

Rats have relatively poor eyesight, especially those with pink or red eyes. They are better at detecting movement rather than static objects. Sometimes, rats may sway to improve their perception of shapes in their surroundings.

4. Male and Female Differences

Male rats tend to be slightly larger with coarser fur, often relaxing while being stroked. Females are generally more active and inquisitive. Understanding these behavioural differences helps in providing tailored care.

5. Rats Can’t Vomit but Can Regurgitate

Due to a strong valve between their stomach and oesophagus, rats cannot vomit. Occasionally, they can regurgitate partially digested food, which differs from vomiting but is sometimes observed.

6. Playful Young Rats

Baby rats engage in play fighting, wrestling and chasing around from around two to three weeks old, peaking by one month old. As they mature, this behaviour decreases, replaced by more adult social interactions.

7. Adopt Don’t Shop: Rehome a Rat

If you’re seeking a pet rat, consider adopting from a rehoming shelter or charity before buying. Many homeless rats wait for loving homes, and adopting supports responsible pet ownership and reduces demand for pet shop sales.

8. Sensitivity to Electromagnetic Fields

Rats are highly sensitive to electromagnetic fields emitted by TVs, kitchen devices and other electrical equipment. Keeping their enclosure in a low-electrical environment helps reduce stress and promotes wellbeing.

9. Safe Bedding Choices Matter

Softwoods such as pine or cedar can release harmful phenols harmful to rats, potentially causing kidney, liver and respiratory issues. Use safe hardwood shavings or paper-based bedding to protect your pet’s health.

10. Rats Sense Human Moods

Rats are attuned to their owner's emotions, especially negative feelings like stress or fear. Handling your rat when you are calm and happy encourages trust and a secure bond between you and your pet.

11. Rats Need Companionship and Attention

Highly social by nature, rats thrive when kept with at least one companion, ideally same-sex unless breeding is intended. They enjoy affection and socialisation, often having favourite spots they like to be petted. Avoid the base of the tail as it can be sensitive.

Rats are intelligent, social, and fascinating pets. Understanding their needs and behaviours helps ensure you can provide a happy, healthy life for your clever companion.

By adopting or buying from reputable sources, providing safe environments, and offering companionship, you support responsible pet ownership and enjoy the unique rewards these delightful little animals offer.
