Fruits like orange, grapefruits, and lemons are good for female rats, but many rat fanciers avoid feeding these fruits to males due to a risk of cancer from the peels. Some rat owners also avoid papaya and mango for the same reasons. Raw veggies like sweet potatoes, cabbage, and brussels sprouts can be toxic and harmful but are fine once cooked. 

The most important is to keep a balanced diet for everything your pet mouse should take and also keep a check on the quality and quantity of food that you are feeding your pet mouse with.

Fruits and Vegetables (Avoid)

Don’t give apple seeds or the pit of any fruit to your pet mouse for eating. Do not feed your pet mouse with avocado skin. Do not provide green bananas and potatoes with green skin.

Store Food

While you are going to buy food for your pet mouse, search for a diet that has been made specifically for a pet mouse. This will usually be a balanced diet since they have historically been considered the best mouse diets. Loose seed mixes are very well-balanced diets, but only if your pet mouse eats everything in the mix. 


Pet Mouse loves to eat watermelons just as much as we humans do. These fruits can even be good for your pets because they are very rich in minerals and water and can be very good at keeping yourself and your pet mouse hydrated on hot summer days. But you need to be careful of the amount of watermelon you’re feeding your pet mouse. Watermelons have a high amount of sugar and minerals in them. Sugar isn’t good for a rat. Try to know about the fruit and its benefits as well as its side effects.

But like we discussed above, a couple of small pieces won’t hurt your pet mouse. Just give them as a treat and not a full meal. It’s easy to feed watermelon to pet mice. And not like other fruits, you don’t have to be worried about which part is right for them and which is not. All three slices of a watermelon, the outer rind, the flesh, and the seeds spread in the flesh are all okay for a mouse to eat.

Pet mice are very easy to look after and take care of. But one of the few responsibilities you have as an owner is to make sure you’re giving it the right food and the right amount of quantity as well as good quality. Your best bet is to create a diet consisting of a bulk (between 80 to 90 percent) of store-bought mouse pellets. The remaining 10-20 percent can include treats like vegetables and fruits (watermelons included).
