Sometimes — with care
Ripe tomato flesh is a safe occasional treat for rabbits. Every green part of the plant — leaves, stems, unripe fruit — is toxic to them. Garden access needs fencing.
A ripe tomato is just another sugary “fruit treat” for a rabbit: fine in small amounts, counted in the weekly fruit budget. The tomato PLANT is a nightshade, and its solanine-bearing leaves and stems are genuinely toxic to rabbits — more of a practical risk than for dogs, because free-roaming garden rabbits graze. Seeds in a slice of ripe tomato are harmless at rabbit portion sizes.
A wedge or a cherry tomato once or twice a week, max. Remove any green parts. If your rabbit grazed on tomato plants in the garden, call an exotics-savvy vet — and fence the vegetable patch.
For daily vegetables, stick to leafy greens like romaine, coriander and parsley — tomato stays in the treat column.
