Tomato

Cats are sensitive to glycoalkaloids, so leaves and green fruit must be avoided entirely; ripe flesh is not recommended as a routine treat either.

Tomatine and related glycoalkaloids

Drooling, vomiting, lethargy, unsteady walking.

Seek care immediately if foliage was eaten; a small amount of flesh only needs observation.

Many cats chew tomato leaves on balconies - use a physical barrier.

Ripe red flesh usually causes only mild stomach upset, but the leaves, vines and unripe green fruit contain tomatine and related alkaloids that in larger amounts can affect the gut, nervous system and heart rhythm.

Tomatine and related glycoalkaloids (highest in leaves and unripe fruit)

Drooling, vomiting, diarrhoea, reduced appetite, lethargy; after large amounts of foliage, abnormal heart rhythm, weakness and tremors.

A small amount of ripe flesh can be monitored; contact a vet immediately if leaves or green fruit were eaten, stating the amount and plant part.

Fence off tomato plants in the garden or on balconies and clear fallen leaves; even ripe flesh should be cored and cut into pieces.
