New Kitty

Here are a few guides, I'd usually write  the explanations myself but I'm short on time today.

My cleaner's sister just called me; asking me to give her milk, rather than water.

She just went into the litter tray, which is a positive sign. But she's still scared. 

You say she is scared? Did she possibly have an adverse interaction with another human before she came to you that could have made her wary of people? In a funny way I often think cats are a bit like autistic people, in that what causes our trauma isn't always obvious, our reactions can be very extreme, and it takes time and patience from our loved ones to heal from it. Also the not wanting to be touched unless it is on our own terms. We can be very cat-like and vice versa.

Yes, she's now in the shed; fortunately, I was able to carry her. But she's still hiding, and hissing.

A friend says that I need to be with her, gradually edging over, for three hours. And I don't have that time; with my Zoom commitments.

However, my cleaner will be here; tomorrow morning. She'll help.
