I got up this morning to find someone- mentioning no names but I suspect Fish, who is a stray who depends on us for food/shelter at times, and can climb over the cat proof fencing around the garden to get into the house- had brought in an old chicken bone. And naturally one of my crew had picked it up and brought it upstairs to play with. I'm scared to death one or several of them will have been chewing on it, especially since years ago we nearly lost one of our cats after he sneaked a bone and it splintered in his gut. I'm neurotic about bones, they NEVER go outside or anywhere else any animal could get near them. This one looks ancient and must have been brought some distance, I'm hoping this old it might not have been interesting enough to chew on. Can anyone give me some clues about what to look for if any of my cats have been hurt by this horrible thing? They all ate and drank fine this morning, and thankfully I'm not working this week so I can be around to keep a close eye on them. ANY suggestions would be appreciated, I'm really worried.
