子猫の代表的な重さは約 0.5 キログラムです。原文の抜粋(英語):Only the tiniest of tiny baby kittens fit in this category. A baby kitten that is one to two weeks old weighs about a hundred grams so that you can have five of them for 500 grams.
If you find yourself the owner of a litter of five baby kittens, they should weigh about 500 grams; if they don’t, you might want to take them to the vet to make sure everything is okay.
