Obviously feral cats catch birds, mice, rats, rabbits, moles and eat them including the bones. No one can determine whether any intestinal perforations, injured intestinal linings, or bone compaction in the intestines happens to feral cats. However, feral cats adhere to survival of the fittest motto and are the toughest cats.
Veterinarians usually do not recommend feeding domestic dogs or cats bones or meat with bones in it because veterinarians see many pets with bone ingestion related problems in practice.
The doctors at St. Louis Cat Clinic do not recommend feeding cats bones because we see problems when cats ingest bones. Not every cat will develop a problem, but enough do that it is prudent not to feed bones. Cat people need to protect their cats from bones placed in garbage because those pesky cats will dumpster dive to get them. Covered trash and garbage cans are recommended to prevent bone ingestion in the home.
