Evening all.
Bit of a traumatic weekend. On Saturday, at around 12.30, we went out to meet friends.
Digby was, fine, had eaten his breakfast, enjoyed a good ponce about in the sitting room, "helping"
to sort the decorations as I took them down.
When we returned at 3.30, he was collapsed on the doorstep. Dash to the emergency vet, with me thinking a couple of times on the journey that he had died 
He was put on a drip, kept warm etc, vet thought it was either poison or a pulmonary embolism.
He had scans, fluid drained from his lungs, blood tests, more scans. They wanted to refer him to the vet school at Bristol, because they still couldn't be sure what was wrong.
Anyway, he has now been diagnosed with a severe heart condition, will have to have various pills every day (Please do NOT post the "how to give a cat a pill thing) and the vet has advised that even with this, his life expectancy is months, not years. 
Bless his cotton paws, he's only 7 years old. We have had him since he was 2, a Cat's Protection boy, as is Oliver Sprout.
Mr P is so upset, as indeed am I.
Long term members may have read some of my posts about him, he is quite definitely NOT the brightest cat on the planet, but much loved.
