Why 5 kg doesn't outweigh these risks
While a larger cat has more body mass to dilute toxins, the seasoning and gravy concentrate the danger. A 2-inch skin piece packs enough fat to potentially trigger pancreatitis—an inflammation that isn't size-dependent. The salt content alone could exceed her daily limit by 300%.
Onion and garlic powders damage feline blood cells at 5 grams per kg of weight. Though she likely didn't hit that threshold, cumulative exposure from future incidents could. Her weight buys time, not immunity.
The critical first 90 minutes
Fat absorption starts rapidly, so watch for lip-smacking or restless pacing—early nausea signs. Don't wait for vomiting to act. Confine her to a room with water and a litter box, allowing observation without household distractions.
Seasonings often cause delayed reactions (6+ hours), but grease hits faster. If she starts panting or adopts a 'praying position' with front paws down, her pancreas may be struggling. These signs warrant immediate vet contact regardless of the hour.
How skin changes the equation
Cooked turkey skin is nearly 40% fat—far denser than meat. When cats ingest high-fat foods, their gallbladders over-release bile, potentially causing yellow vomit or diarrhea. The skin's rubbery texture also resists stomach acid, slowing digestion and prolonging exposure.
Gravy adds emulsified fats and salt, creating a double burden. Even if she keeps it down, expect thirst and possibly louder gut sounds as her system scrambles to process this unfamiliar load.
When to escalate beyond watching
Three vomits in an hour or diarrhea with visible blood streaks mean her system is overwhelmed. Dehydration from fluid loss becomes the secondary threat. Press her gums gently—if the white mark takes over 2 seconds to pink up, circulation is struggling.
Less obvious is lethargy developing after initial hyperactivity. This could signal blood cell damage from seasonings. Time matters: onion toxicity signs often appear 24-48 hours later when owners assume the danger passed.
