What a tongue's surface area picks up from sauce
A cat's tongue transfers minimal amounts when licking - we're talking fractions of a milliliter for a single pass over butter sauce. At 8 pounds, your cat would need to ingest about two tablespoons of pure butter to risk pancreatitis, so this incidental contact isn't a dosage concern. The bigger variable is what else was in the sauce - garlic powder or onion granules would be more problematic than dairy alone.
Watch the spot she licked - if it's just a shiny film rather than a pooled sauce, the actual consumption was negligible. Cats' sandpaper-like tongues are designed to scrape meat off bones, not lap liquids efficiently. You'd likely see more butter on her whiskers than actually swallowed.
Butter versus other dairy for feline digestion
Butter contains almost no lactose compared to milk or cream, which is why small amounts rarely cause issues. The high fat content (80% in butter versus 3-4% in whole milk) does stimulate stomach acid production, but in this tiny quantity, it typically just enhances appetite rather than causing distress. Your cat might vocalize more or rub against food containers within the hour - this is normal food-seeking behavior, not discomfort.
What makes butter different from plain lobster meat is its coating effect. If your cat had preexisting acid reflux (common in brachycephalic breeds), even this small amount could temporarily worsen regurgitation. Listen for wet-sounding gulps or observe if she stretches her neck repeatedly - these are subtle signs of esophageal irritation.
The 30-minute to 2-hour window for reactions
Most sauce-related stomach upsets begin showing within half an hour if they're going to occur. The first signs would be exaggerated swallowing motions or floor-licking - your cat trying to clear residual butter from her mouth. True vomiting from such minimal intake would be unusual unless she has a known sensitivity.
Diarrhea would take longer to manifest - at least several hours for the butter to transit through the system. Monitor litter box habits tonight and tomorrow morning, looking for unusually soft (but not liquid) stools. The high fat content may give the feces a shinier appearance temporarily.
When licking becomes problematic behavior
The psychological aspect matters here - if your cat successfully scored human food once, she may become more persistent about begging. Lobster aroma is particularly enticing to cats because it contains amino acids similar to their favorite fish. After this incident, be extra vigilant about leaving plates unattended during meals.
Watch for new counter-surfing attempts or prolonged staring at the dining table. These aren't medical concerns but rather behavioral ones to curb early. Offer an approved seafood-flavored treat when you eat lobster to create a safer association. The goal is to satisfy the curiosity without reinforcing the unwanted behavior.
