Before You Buy
Key Buying Factors
01
Form: Pellets vs. Mix
Pellets or blocks prevent selective eating, ensuring your rat gets complete nutrition. Seed mixes can lead to obesity and deficiencies if rats pick out high-fat seeds first. For most rats, a high-quality pellet should be the base diet.
02
Protein and Fat Content
Adult rats need around 14-16% protein and 4-6% fat. Too much protein can cause kidney issues, while too much fat leads to obesity. Growing or nursing rats may need slightly higher levels.
03
Fiber for Dental Health
Rats' teeth grow continuously, so a diet with fiber-rich ingredients like hay encourages chewing and helps wear teeth down. Look for foods with timothy hay or other plant fiber.
04
No Added Sugars or Fillers
Avoid foods with added sugars, corn syrup, or artificial colors. Rats can develop diabetes and obesity from sugary diets. Stick to foods with natural ingredients and no empty fillers.
Living With It
Care, Cost and Maintenance
Feeding Schedule
Provide fresh food daily. Adult rats eat about 1/4 to 1/2 cup of pellets per day per rat, plus fresh vegetables. Remove uneaten fresh foods after a few hours to prevent spoilage.
Fresh Supplements
Offer small amounts of fresh vegetables (e.g., broccoli, carrots, leafy greens) and occasional fruits (e.g., berries, apple). Avoid citrus and raw beans. Fresh water must always be available.
Treats and Foraging
Use low-sugar treats like plain popcorn, pasta, or commercial rat treats sparingly. Hide food in foraging toys to encourage natural behaviors and mental stimulation.
Pro tip
Our team suggests introducing new foods gradually over a week to avoid digestive upset. Monitor your rat's weight weekly and adjust portions if they become overweight.
Frequently asked questions
Can I feed my rat dog or cat food?
No. Dog and cat food lack the proper balance of nutrients for rats, especially vitamin D and taurine. Stick to a formulated rat food to avoid deficiencies.
How much should I feed my rat each day?
Adult rats typically need about 1/4 to 1/2 cup of pellets per day, plus fresh vegetables. Adjust based on activity level and weight. Always have fresh water available.
Do rats need vitamin C supplements?
Unlike guinea pigs, rats can synthesize their own vitamin C, so supplements are not necessary if they eat a balanced diet. However, providing fresh veggies adds variety.
Is seed mix bad for rats?
Not necessarily, but rats often pick out seeds and leave less palatable pellets, leading to an unbalanced diet. If using a mix, offer it in small amounts as a treat alongside a pellet base.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
