Vets recommend keeping all treats under 10% of daily calories. One small piece of romaine lettuce has about 1 kcal. The chart shows the most a typical spayed or neutered adult cat could have in a day if lettuce were the only treat.
| Cat weight | Daily treat budget | Max lettuce per day |
|---|---|---|
| 6 lb (2.7 kg) | 18 kcal | 17 × small piece of romaine lettuce |
| 8 lb (3.6 kg) | 22 kcal | 22 × small piece of romaine lettuce |
| 10 lb (4.5 kg) | 26 kcal | 26 × small piece of romaine lettuce |
| 12 lb (5.4 kg) | 30 kcal | 29 × small piece of romaine lettuce |
| 14 lb (6.4 kg) | 34 kcal | 33 × small piece of romaine lettuce |
Eating more than the recommended amount usually causes nothing worse than an upset stomach: soft stool, gas or vomiting. Skip treats for the rest of the day, keep fresh water available and call your vet if vomiting or diarrhea lasts more than 24 hours or your cat seems unwell.
