just had vet on the phone ( he phone me!).... apparently she may have gone to the toilet (wee) over night, although they don't know if it was just incontinence or conscious effort.... So he has made a suggestion to amputate tail, which he has now gone off to do..... They have had to take the food away because she is eating too much!!!! She has not, however done a poo.. so it is still a wait and see process... but he has agreed that may be we give her til the weekend b4 making "that" decision... she is quite happy and responsive and bright so...who knows.... mustn't get hopes up tho....
