⚠ If your cat ate plastic
Act immediately — don't wait for symptoms.

Swallowed plastic is one of the most common reasons a dog ends up having emergency abdominal surgery, and unlike most items on this list the danger is almost entirely mechanical rather than chemical. What matters is the shape, the size and the edges.
How much is safe?
There is no dose to calculate, only a risk to judge. Soft film — a sandwich bag or cling wrap — often passes, but can also bunch and obstruct. Hard fragments from a chewed toy, a bottle cap or a container lid are worse, because rigid pieces with edges can perforate the gut wall. Anything wider than the narrowest part of your pet's intestine will not pass, and in a small dog or a cat that threshold is startlingly small. Plastic wrap that smells of food is swallowed enthusiastically and in quantity.
What happens if a cat eats too much?
The obstruction pattern is fairly consistent: repeated vomiting, particularly soon after eating or drinking, refusing food, lethargy, a hunched or 'praying' posture, straining without producing stool, and a tense, painful belly. If a sharp piece has perforated the intestine, deterioration is faster and includes fever and collapse. Some pets are bright for a day or two before declining.
⚠ What to do if your cat ate plastic
Call your vet as soon as you know or suspect it (ASPCA 888-426-4435 · Pet Poison Helpline 855-764-7661 for out-of-hours advice). If it has only just happened, a vet may be able to induce vomiting safely in the clinic — do not attempt that at home, especially with hard fragments. Be aware that most plastics do not show up on a plain X-ray, so ultrasound or contrast studies may be needed. Bring an identical item if you have one, so the team can judge the size and shape.

Frequently asked questions
My dog ate plastic wrap and seems fine — do I just wait?
Call the same day and watch closely for 48 to 72 hours. Vomiting, appetite loss, straining or belly pain mean go in immediately rather than continuing to wait.
Are some plastics toxic as well as obstructive?
The obstruction is almost always the real issue. A chewed bottle of household product is a different situation — then the contents matter more than the plastic.
