My newborn kittens are different sizes. Is the small one getting enough milk?

Pet's info: Cat | Domestic Mediumhair | Female | unspayed | 5 lbs

Pixie has devlivered 2 healthy kittens they are two days old. The little boy weighs 160grams The little girl weighs 100grams So there is quite an obvious difference in weight and size I have a concern that the biggest is pushing the little one away from the nipple during feeds. I have heard about using kitten replacement powder but can’t get any at the moment due to the pet shop being closed. What can I use as a teperary measure?

A newborn kitten usually weighs about 100g. So the small one is a normal weight and the big one is really big. They will gain about 100g/week. So if your smaller kitten gains about that much/week, it is getting enough milk. Mama has more nipples, so it will likely be able to drink while the other is suckling somewhere else. Just observe them. For now I would not worry.
