What happens if my 4 kg cat nibbles green potato peel from the compost bin every few days for

Short answer

Repeated small doses of solanine from green potato skin can build up and cause chronic poisoning. Over weeks, you might see intermittent vomiting, loss of appetite, and a general lethargy that owners often mistake for 'just getting older'. The toxin also affects the heart and nervous system — long-term, this can lead to weakness, tremors, or an irregular heartbeat. Stop her access to the compost bin immediately. If she's been doing this for a while, a vet check is wise to rule out any accumulated damage, even if she seems fine right now.

Green or sprouted potato should not be given to cats at all. Even a small amount can do harm, so there is no portion small enough to be safe.

Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.

Green or sprouted potato has no place in everyday feeding: keep the rest of the day's food unchanged after this and watch the litter box and how quickly they finish the next meal.
