Hello there.. I need some help I have three lovely cats two female age 11 months and one year and a male 7 months.Now my year old cat is on heat. And out of the blue my 7 month old male is buging my 11 month old cat. I don't get it. Is my 7 month male on heat and if he is why is he bugging my cat which is not even on heat. And the one which is on heat he is not even looking at her. Plz advice
