Thanks everyone
No, he is not home, Vet wants to keep him overnight again as he has not eaten or been to the toilet, and if he is taken off the drip he might go down hill again over night. If he has still not eaten or been for a pooh by tomorrow they are going to X ray him to see if he has a blockage. Got to ring again in the morning.
Thank goodness for insurance.
Just a mention for anyone with M & S insurance, my policy changed on renewal (and of course I did not read the small print). It now states that you are supposed to ring their pet insurance out of hours number before you use an out of hours vet service
I 'phoned them this morning and as my vet had told me to go back if Bailey got worse I will still be covered for the out of hours treatment.
