I used to volunteer for an animal rescue centre. I'd definitely call the RSPCA or equivalent. The situation you described is negligent & the animals need immediate attention. If they've been left without water that is a basic need & demonstrates that either she has deliberately neglected them and/or she herself is in trouble. You may need to call more than one animal rescue centre before some-one sits up & listens to you. I know you're shattered today hun but those 2 furrballs need some-one to speak up for them.
On a different note, you're welcome re the blossoms painting. I knew I needed to send you an image of it. It has huge sentimental meaning for me. I bought it when I was going through my 1st rounds of IVF about 7 yrs ago and now represents the long journey to get that one small miraculous poppet.
