Yep, he did. I had pinned the lining back into an oven glove so it wouldn't come out in the wash. Hoover stole and shredded the glove, Keepurr ran off with a section of fabric and the pin. I ran all around the (large) garden but no sign of him. Eventually he came for TRADE ! and dropped the pin and fabric. Hoover picked it up, again TRADE worked and she dropped it. But this time Keepurr was not going to be fooled, I couldn't move quick enough and he swallowed the lot Chewing as he did so.
I fed him three slices of bread (to cushion the pin) and called the Vet. The bread, while being a sound move, would also block an endoscopy but he said it might well come out in (of) the end within two or three days, if not, bring him in for X-ray.
I followed him around for a couple of days. He ate, drank, defecated completely normally and I wondered if I'd missed something. Eyes were bright, gums the right colour, fur felt good, but I needed to be on the safe side so Thursday - to the Vet he went.
X-ray revealed the pin, bent and open. Keepurr was admitted immediately for surgery. Because it was bent and open the pin hadn't moved out of the stomach and when he went in, the Vet found the fabric had spiralled itself around the point of the pin and was protecting the stomach from perforation.
Keepurr came home that night on liquid diet and then low residue soft food, tiny meals several times a day because he has a 5 inch long incision in his stomach. He is bright, alert, and starving hungry.
The Vet warned me he might have diarrhoea and to a small extent, he did the first night.
But - and this is my problem (!) - how to clean his rear end ? I have tried with canine medicated shampoo, but he is unhappy about standing still and the area is pretty caked with dried faeces in the fur. I got some out this morning, accompanied by growling but I can't pick him up cos of the stitches (more growling !). It is going to have to be cleaned before he gets to come into the lounge to watch TV in the evenings.
Several years ago, when Keepurr ate a fleece-lined leather glove, the same Vet removed it and at the time I suggested he put in a zip-fastener.
