What Should we feed our Rat?
Rodent blocks – blocks of food made for rats/rodents in mind. It is preferred that corn is not the first ingredient. Blocks are made for chewing and help keep your rats teeth from overgrowth.
Harlan – Teklad
Other types, read labels (try to find blocks made for professional use - labs, etc)
Rat & Mouse mixes-
Hamster, Gerbil, Guinea Pig mixes – Not suitable for rats
Homemade, mixing Your Own:
If you decide this is the way to feed your rat, please make sure the ingredients will fulfill a rat’s Recommended Daily Allowance.
Listed below are only suggestions!
This is what WE feed our rats along with Mazuri rodent blocks:
3 Parts grain mix
2 parts Rolled oats
1 part Rolled Barley
1 part Rolled Triticale
1 part Rolled Rye
(Bulk, rolled grains are used rather than whole grains for digestibility)
1 Part dry dog kibble
We use Diamond Senior, lowfat OR use a high quality, low fat brand with moderate protein content (14-20%)!!
1/2 part ABC Pasta Soup Mix
(consists of lentils, pasta, green & yellow split peas, rice with no spices)
Above is approximately 14.6% Protein & 5.07% fat *
Other items you can add to diet:
Use in small quantities~
Split peas, legumes
May add too much sugar to diet depending on rat, use in
How much and how often?
This has a lot to do
with the size of your rat.
10 oz rat will eat up to ½ ounce
284 g /100 = 2.84 x 5 g = 14.2 g or ½ ounce
1 lb ¼ oz rat will eat up to 1 oz
567 g / 100 = 5.67 x 5 g = 28.35 g or 1 oz
Treats and Snacks
Chewies – Good for teeth
Nylabone flavors – Carrot or others
Dog biscuit bones
Treats – minimum use
Rats need 10 ml per 100 grams of body weight per day. So for a 300 gram (10.5 oz) rat, they would drink approximately 30 ml of water or 1 oz per day. Use plastic or glass water bottles that can be washed and cleaned at least weekly. Water should be kept fresh.
What not to feed
Carbonated sodas – rats cannot burp
Sticky foods - peanut butter, can cause choking
Candy, Ice cream, & junk food
Rats are just like us and love to eat sweets.
Salty & spicy foods
Raw sweet potatoes
Raw: cabbage, Brussel sprouts, Artichokes, tofu
