We do get a lot of people contacting us re: caring for wild baby rats that they have found.
Babies are born hairless with their eyes shut and will open their eyes at around 14 days.
Keep them warm and safe in a cage with narrow bars or a well ventilated tank, away from any other household pets.
In the early days, feed lactol which is a small animal / kitten milk, from a pipette; cotton bud; or rubber glove finger pierced at the end. When taking milk, if they open their mouths really wide, this means they are enjoying it. If milk comes out of nose, then stop – you could choke or drown their lungs.
After the baby has eaten / drunk, stimulate their genitals in order to make them pee and poo. Use a warm cotton bud and rub it over their bits (this is what their mum would do to make them go to the loo).
Once that the rat’s eyes are open, start feeding mushy foods plus the milk. Weetabix, baby food etc
Then introduce traditional rat food with cereals thrown in as well as seeds to accustom them to a wild rat diet. Put mealy worms in some spoil to encourage them to dig for wild food.
Some people do go on to keep their wild rat and tame them. Others will release them somewhere safe at around 6 weeks.
