Why wobbliness changes everything for a 3 kg cat
When a small cat shows unsteadiness after eating raw egg whites, it suggests her nervous system is involved — this isn't just stomach upset. The combination of vomiting and loss of coordination means her body is struggling with more than simple digestive irritation. At her size, even small amounts of avidin (the protein in raw whites that causes issues) can have outsized effects compared to larger animals.
Muscle tremors or weakness often follow wobbliness in these cases, which is why timing matters so much right now. The first hour is when symptoms either stabilize or escalate, and we're already seeing concerning progression. Don't attempt home remedies; her small body weight makes dosing anything risky without professional guidance.
The dangerous overlap between vomiting and neurological signs
Two vomiting episodes in an hour point to active rejection of the egg whites, but when paired with wobbliness, it indicates the problematic proteins have already started absorbing. Unlike dogs, cats lack certain digestive adaptations to handle raw egg components efficiently. What might cause mild diarrhea in another pet can trigger systemic reactions in felines, especially at this weight.
Watch for subtle changes in her pupils or how she holds her head — these often appear before full muscle tremors. The wobbly gait suggests temporary interference with nerve signals, which could worsen if her body continues absorbing avidin. Keep her in a quiet, dim space to reduce sensory stress while arranging urgent care.
Why waiting isn't an option at this stage
Some toxins allow for observation periods, but neurological symptoms shift the calculation entirely. What makes this situation urgent is that we're already past the point of simple stomach irritation. The proteins affecting her nervous system won't be 'vomited out' at this stage — they're circulating and need professional intervention to prevent further absorption.
Her 3 kg body has less reserve to handle metabolic disturbances than a larger animal. Small cats dehydrate faster from vomiting, and electrolyte imbalances can amplify the neurological effects. If she starts panting or her gums look tacky, these are late signs — we want intervention well before that point.
Preparing for the vet visit with specific observations
Note exactly when the wobbliness started relative to the vomiting — did it appear between heaves or after both episodes? Time stamps help the vet assess toxin progression. Check her paw grip strength by gently seeing if she resists when you pull a paw sideways (don't force it if she's unsteady). Weak resistance correlates with advancing neurological impact.
Bring a sample of any remaining egg whites if possible — the vet may check whether other contaminants could be involved. Expect them to ask about her water intake since vomiting began and whether she's attempted to use the litter box. These details help distinguish between primary neurological effects and secondary dehydration complications.
