The short answer
Texture, scent, boredom or access to outdoor smells can make rubber attractive. Swallowed rubber can obstruct the digestive tract.
What to observe
Check for missing pieces, vomiting, appetite change and when chewing occurs.
How to read the situation
Swallowed rubber can obstruct the digestive tract. Compare the pattern with your cat’s usual behaviour and consider timing, body language, appetite, litter-box use, mobility and recent changes.
What to do now
Block access, provide safe chew-resistant enrichment and repair damaged seals.
What not to do
Do not punish, frighten, force or repeatedly test the cat. Avoid changing several things at once, because that makes the response harder to interpret.
When to contact a veterinarian
Suspected ingestion, repeated vomiting, abdominal pain or no stool needs urgent veterinary care.
What to record
Write down when it began, how often it happens and what occurs immediately before and after. A short video, clear photo, food record or litter record can give the veterinary team useful context.
What to check first
Check for missing pieces, access to condensation or mould, and whether chewing occurs elsewhere. Track appetite, stool and vomiting.

What to do next
