One of the signs cats trust you is they show you their belly, even more so if they let you touch or rub their belly. This spot is a point of vulnerability for them. Their vital organs are there.
Your 8th house is your kitty belly. It’s your zone of vulnerability, intimacy, victimization, death and transformation. It’s where you keep your secrets, parts of you that you protect.
Where the 2nd house is your resources, and experiencing yourself as a resource, the 8th house is the sharing of resources and the way you give yourself to others.
Planets in any house show where you came in investing your energy, including lessons and experiences you believe will move you forward.
