Here's why:
* Relaxation: Lowering the back and making their body more "flat" allows them to relax and fully enjoy the sensation of being petted.
* Trust: This posture shows trust and comfort in your presence. They feel safe and relaxed enough to expose their vulnerable belly area.
* Inviting further interaction: It's often a sign they want you to continue petting them. They may even purr, knead their paws, or rub their head against you.
However, it's important to note that not all cats will exhibit this behaviour. Some cats may be more sensitive to touch and prefer other forms of affection.
Pay attention to your cat's body language:
* Tail: A relaxed, twitching tail is usually a good sign. A puffed-up tail can indicate annoyance or anxiety.
* Ears: Forward and relaxed ears are positive. Flattened ears may indicate fear or aggression.
* Whiskers: Relaxed whiskers indicate calmness. Tense whiskers may indicate nervousness.
If your cat seems uncomfortable or starts to tense up, stop petting them and give them space. Respect their boundaries and let them come to you for attention.
