It’s absolutely vital that you know what foods are ok for your rat to eat, and what foods are not ok. You do not want your rat to become sick from eating foods that are not easily digestible, or worse still, foods that they are allergic too. Pet stores stock plenty of food mixes and treats for rats, but sometimes it’s nice to give your pets something different.
It is always tempting to give some food scraps to your rats that are left over from preparing a meal, or maybe a treat that you are eating. Rats often approach you when you are eating and will reach out, or sniff in your direction and look like they are asking for a bite.
When you first give a rat some new food to try they will often take a small bite then leave it. This does not mean that they do not like it, if you leave the food in their cage you will often see them return to it later. Rats cannot vomit or release gas, so they will be very careful when trying new foods. Taking a small bite and giving it time to digest is normal, they will return to the food if it has not made them unwell.
Apples – It is important that you slice up the apple into smaller pieces and remove all the seeds.
Apricots – I challenge you to find a rat that does not like apricot.
Avocados – These are high in fat and should be an occasional treat, always remove the skin.

These lists are not exhaustive by any means, but a large collection of foods that I have either personally fed to my pet rats, or collected from forums where the source of information is believed to be credible. If you are unsure of anything, or think your rat has eaten something that does not agree with it you should seek professional veterinarian advice.
As a pet owner you have the responsibility to make sure that your pets are eating a healthy, balanced diet. This does not need to be difficult, buying a food mix from a pet store will usually do just fine, and some treats at your discretion will make your rats happier.
All of the foods mentioned in this article that are safe for rats to eat are to be given to them as treats. The bulk of a rat’s diet should be made up from store-bought rat food mixes. These foods usually come as a food mix, or a block/pellet of food. Adding some vegetables and fruits on occasion will help give your rats a balanced diet. This will help them maintain a healthy and happy lifestyle, giving you more fun as a rat owner, and helping build a stronger bond between you and your rats.
