If you don’t have any cherry tomatoes, you can cut up a large one into small pieces. The last thing you want is for them to choke, so it is important that you do this. A quarter slice should fill your pet up nicely.

Monitor them closely

If your rat has a negative reaction of some kind to this food, you’ll want to know about it sooner rather than later. Look for symptoms like diarrhea, lethargy, or vomiting. If you notice any of these things with your rat after they eat the tomato, you should avoid giving it to them in the future. It might also be necessary to take them to the vet to get checked out.
