Verdict: Usually yes, with caveats. Ripe tomato flesh is usually fine in small amounts, but green tomatoes and plant parts contain solanine.

Safe prep first

Use only ripe red tomato flesh, plain and seed-light.

  • Serve it plain, with no garlic, onion, sweeteners, or heavy seasoning.
  • Start small, then wait before offering more.
  • Keep treats under about 10% of daily calories.

Portion and limits

A bite or two, not daily feeding.
