Oh Im very grateful for the questions!
No there is no blood in her poo. When we wormed her there was a little tiny tiny bit of blood (two dots as big as a needles head - yes I had a close look! )
Now her poo is either normal and normla colour or diarea. But thankfully no blood.

The vet checked for a microchip but didnt find one. He told me that he suspects she is an 'old lady' and its best to put her to sleep!!
But I asked him whether it wouldnt be better to worm her and get all the parasites of her (she was covered in them) and then see how she is doing? But he didnt want to do that. He looked at me and said "Nah she doesnt have worms"
I was in shock. Well Im sorry if an animal eats and drinks and poos and wees and is in no pain why put it down?
She doesnt seem to be in any pain. She is alert and cheeky! She is so fixed on the food that she totally blanks what is in her way - and most of the times that is one of my dogs. they wont bite her but I have to keep her from literally walking over my dogs and using them as part of the carpet!

Oh coming back to the poo... She does about three poos a day when she has diarea. This morning her poo was perfect! I was over the moon! But then the next two were diarea.

Sigh...I guess time will tell.
You wouldnt know why her front legs and hest are a bit oily? she is along hair cat and I am starting to wonder whether it has anything to do with the flea collar I put around her...

Oh well at least she is in the warmth has fresh water and food and a clean bed to sleep in. Every time I go outside into the freezing cold I get overwhelmed with sadness...if i didnt catch her I think shed be dead by now. That day I forst saw her... she was a foot away from me, I watched her eat and when she looked up at me she stopped eating for quite some time and just stared at me. It send shivers down my spine. I think I know why now... I could see death in her. she was on her last legs the day I caught her..
