According to the person that looked after them while I was away, Leila never came down for her food or drink, but stayed perched on high hissing at her. She must have had something to eat and more importantly, drink though, or she wouldn't be alive today...but she is just skin and bones at the moment. She used to be such a chubby little thing, too...
I took her down night before last, noticed the top of the kitchen cabinet needed a good scrubbing, and held her shaking, shivering body close to me. After about two hours, she relaxed enough to start purring. I sat with her in my arms for five hours straight. She never moved, except to duck when Manasse came bounding up to whack her one. I put her on top of the linen cupboard and went to bed. The next morning, she was still there -- and stayed there all day.
So last night, I took her down again. Same thing happened. She won't eat or drink unless I handfeed her, and she'll sit motionless in the safety of my arms. Her eyes are big and round and ever watchful, and she shivers every so often -- but she does pur. I took her to bed with me; she huddled under the covers, as close to me as she could. I woke up in the night, she hadn't moved. I woke up this morning, she still hadn't moved.
I put her in the litterbox, she did her business then refused to come out. I took the top off, took her out, put her back on top of the linen cupboard, and came to work.
If there's anyone out there who has any advice to offer, about dealing with a traumatised cat, please help. I'm at my wits end.
