Why is my 6-month-old fancy rat unusually small and growing outwards?

Updated On September 23rd, 2025

Pet's info: Small Animal | Rat | Female | unspayed | 1 year and 5 months old

I have a 6 month old rat named Regi. She is particularly small compared to the others, and I was just wondering why. She is a fancy rat, I’ve also realised in the past week she has been growing more outwards than longer. Hope you can tell me what’s going on.

Thanks for reaching out about Regi and including pictures. By the pictures, she doesn't seem that unusual in size. But individuals can range in size just like people. If you have other rats, are they're any intact males? Widening in the abdomen could be the storage of fat, but also something medical. If you continue to be concerned, seek an examination with a veterinarian. Good luck.
