Why is it risky?
Plastic bags present two distinct hazards: suffocation when cats insert their heads and become trapped (particularly single-use shopping bags), and ingestion risk. Some plastic bags contain slip additives based on fatty acid compounds or corn starch that cats find attractive to lick and chew.
Affected Systems
Digestive · Respiratory
Symptoms
Suffocation: distress, open-mouth breathing, cyanotic (blue-tinged) gums, loss of consciousness. Ingestion of plastic fragments: vomiting, retching, and potential obstruction.
What To Do
Suffocation: free the cat immediately. If unresponsive: emergency vet. Ingestion of small plastic pieces: monitor for 24–48 hours for signs of obstruction. Ingestion of larger pieces: vet visit.
Notes
Store all plastic bags inaccessible to cats, in closed cabinets or tied in knots before disposal. Applies to shopping bags, produce bags, bread bags, and zip-lock bags. Switching to reusable bags eliminates this hazard entirely.
