Why the crunch appeals more than the risk
Cats are drawn to textures, and the crispness of raw cabbage often tempts them more than the taste. For a 5 kg cat, one plain piece is just an interesting mouthful—it's too small to deliver enough of the compounds that can irritate feline digestion. The real concern would be if she'd grabbed a leaf coated in dressing, since oils and seasonings stick to fur and paws, encouraging more licking.
Watch for any excessive lip-licking or head-shaking, which could mean she got a bit of dressing residue. If the cabbage was truly plain, the only aftereffect might be a slightly noisier digestive system tonight. Skip the next scheduled meal if her belly seems unusually round, but water should stay available.
When party foods become a chain reaction
BBQs are high-risk zones not because of vegetables, but due to the domino effect of stolen bites. A cat who succeeds with cabbage may go for onion-laced kebabs next. Check the area for dropped skewers or corn cobs, which are more dangerous than any salad ingredient.
If your cat is the type to explore tables, consider confining her during meals. A single cabbage theft isn't worrisome, but repeated scavenging could lead to a mix of problematic foods. Her small body weight means even modest amounts of toxic items add up fast.
The gas myth versus reality
While cabbage has a reputation for causing gas, it takes far more than one bite to affect a cat. Their short digestive tracts process plant matter differently than ours, so minor flatulence might occur but won't distress her. True discomfort would show as crouching with a hunched back or refusing to lie down.
Unusual postures or vocalizing are the signs to call a vet, not just a bit of rumbling. For perspective, a 5 kg cat would need to eat a quarter of a raw cabbage to risk real bloating—that's about twenty times what fits in a typical snack.
Post-party monitoring made simple
For the next six hours, note her litter box trips. Diarrhea is unlikely from this tiny amount, but any straining or mucus in the stool means her system is irritated. Normal play and napping mean all is well; hiding or lethargy don't.
Prevent future raids by offering cat-safe crunch alternatives like freeze-dried chicken bits during human meals. The appeal is similar, and it keeps her away from risky buffets. Remember, vigilance with plates matters more than panic over this veggie incident.
