Cat owners are emotional after learning why cats like being groomed with a damp toothbrush. This trick is popular on social media and relaxes cats. Experts say there's a reason for this behavior.

A cat behavior specialist says toothbrush bristles are like a mother cat's tongue, which kittens find comforting. A TikTok user tested this and their cat seemed at ease.

The cat's eyes seemed to well up, making viewers emotional.

Cat behavior expert Jackson Galaxy says a toothbrush is great for relaxing cats. It's used on feral kittens to help them relax.

Jackson Galaxy says it works because it reminds cats of their mother's grooming.

Other experts warn owners not to get too excited about this theory.

Dr Jacklyn Ellis says the reaction may not be due to the toothbrush.

She says cats have scent glands where they like to be touched, which may be why they enjoy the petting.

Dr Ellis advises owners to pay attention to their cat's body language and stop if they show discomfort.

Knowing how your cat feels is important. Experts say there are warning signs if your cat is not enjoying something.

If your cat grooms excessively, hisses, or displays wide pupils, it may be stressed. Ears pinned back or avoiding interaction are also signs of stress.

Cats Protection says understanding feline body language is essential for trust.

They advise against staring at your cat, as this can be threatening. Slow blinking and soft movements can help.

The toothbrush trick has opened up a conversation about how cats experience affection and their early bonds with their mothers.
