So a little more lore into my kitsune now. After a while of looking into his magics and his powers of transformation he comes to realise that he requires alot of positive ki to manage his forms. Usually the larger the form he takes the more he requires. His ki can be acquired in multiple ways Most of which is helping his friends and supporting them by dispelling any negative thoughts or feelings they have and being there to help them. The way he does this can be done in multiple ways either just cuddling or speaking with them but some also prefer the safety and support of being within him, listening to his heartbeat and letting the world fade away and being kept snug and safe within. His body takes the negative ki their body naturally gives off and filters it into positive allowing him to use this energy to shift forms with greater ease. Ofcourse this works in reverse to. If he finds himself either out of positive ki or is unable to filter the negative his form would grudually shrink or even change shape to show this off the scale usually goes something like this.

Lowest ki -> Highest

Spirit -> Micro mouse -> Sized up mouse -> Kitsune (neutral and most common form) -> Eastern dragon (anthro) - Eastern dragon (feral)
