What the vomit reveals about toxin absorption
Vomiting this soon after ingestion suggests her stomach is reacting to both the solanine and the peeling’s physical irritation. Look for thread-like plant fibers or green flecks in the vomit—these confirm she didn’t just lick the surface. Time-stamp when it happened; rapid expulsion may mean less toxin was absorbed.
Don’t clean the vomit yet. Scoop a sample with a plastic spoon into a ziplock bag. The texture matters—foamy white indicates stomach acid activation, while yellow bile means she’s already emptied her stomach contents.
Why a 3 kg cat can’t wait for more symptoms
Cats metabolize solanine differently than dogs—their smaller liver size makes them less efficient at processing plant toxins. Even this single episode of vomiting could precede rapid weakness. Lift her gently; if her limbs feel limp or she resists being held, her muscles are already affected.
Check her third eyelids—those pale membranes at the inner corners of her eyes. If they’re partly covering her pupils, her body is diverting energy to core functions. This is a vet-now sign, not an observe-overnight one.
The danger of assuming it’s ‘just’ vomiting
Solanine doesn’t always cause repeated vomiting like other toxins might. One intense episode followed by eerie calm can mean the toxin has moved beyond the stomach. Press lightly beside her ribs—if she tenses or meows, the peeling may have triggered intestinal spasms.
Watch her litterbox for diarrhea with a peculiar sweet smell. This metabolic byproduct signals her system is struggling to break down the toxin. Normal-looking stool doesn’t rule out trouble—solanine often constipates cats first.
How to transport a nauseous cat safely
Line her carrier with a towel you don’t mind discarding—she may vomit again from car motion stress. Skip the bedding; bare plastic is easier to clean if she has diarrhea en route. Cover three sides of the carrier with another towel to reduce visual stimuli that could worsen her nausea.
Bring her medical records if you have them handy. Cats with prior kidney issues—even resolved ones—need different fluid support protocols. Mention any supplements too; some interact with anti-nausea medications.
