Rats are a genus of rodents in the mouse family. They have become favorites and friends of people for a long time. It is worth taking into account their special fertility. And if you keep individuals of different sexes, then sooner or later they will produce offspring. The question immediately arises: "How to find out about the pregnancy of a rat?" Several signs presented below will help to determine it.
Instructions
Step 1
The onset of pregnancy in a rat is indicated by the absence of another estrus. This is the most objective sign.
Step 2
Look at your pet's behavior. Indeed, at the very beginning of pregnancy, the behavior of rats changes. They become slower and calmer. Some individuals may begin to behave aggressively towards the male.
Step 3
Take a look at the rat. During pregnancy, it becomes slightly rounded, the belly increases slightly, becoming wider in the region of the ribs. Over time, the contours of the female's body change. It becomes pear-shaped (sharp muzzle and expanding belly). The changes are especially noticeable when the rat stands on its hind legs.
Step 4
You can feel your pet's belly. It is worth doing this after 2-3 weeks from the expected, but never started estrus. By this time, it should increase markedly. And if you touch the female's tummy shortly before giving birth, you can feel the movements of the future rat pups. However, in females covered for the first time, this is not recommended.
Step 5
Pay attention to the fact that after becoming pregnant, the rat begins to intensively and carefully equip its home. Pieces of cloth, paper, dry grass should be placed in the cage. After all, it is from this that the rat will build a nest. Do not disturb or try to pet her at such an important moment. You run the risk of being scratched and bitten.
