OH NO! POOR BABIES. DOESN'T LOOK TOO BAD THANKFULLY
We already remove that rat from our house and we doing same for food like u said we also use luke warm water for them and sure I will take them to specialistI guess you should take this babies to a reptile specialist. Rat bites contain poison, so I am not sure if just a cream is enough. Other thing you might need to take care is, the skin is exposed, that means it can get infected. You need to keep it clean all the time. Do not soak them under hot water as it will cause pain in their skin. Use luke warm water. Try not to keep food around them, feed them and after they are done, remove the food from their surrounding. Food will attract flies, and exposed skin is a perfect place for mosquitos and flies to lay egg. It may cause an infection. Also buy those rat traps so that this may never happen again.
