I am sorry I am not a native speaker so please bear with me :). I have a 3-year-old female cat.
Two months ago, she went into heat like always, but she developed a new habit this time...
She keeps meowing all day long (nothing unusual till now) until I pick her up and give her a belly rub (which she used to hate a lot,) and then she relaxes and sleeps on my lap.
This habit became more strange. For two months, she was following me everywhere in my house meowing loudly (especially at night). She even jumps up and opens the door of my bedroom then gets under the blanket and wakes me up with some bites or knocks to my head till I rub her belly, then she sleeps while I rub her belly.
What I know is that she became so connected to me, but what makes me worried is that she always licks her belly while rubbing (or between rubs) till her lower nipples are red and seem irritated.
The vet said normal stuff like try changing her diet, and he pointed that this might be from boredom.
I am very worried that there might some pain in that area that goes away temporarily when I rub her belly.
Is this something that I should be really worried about?
