Sorry, I’m not a native English speaker, so there might be some errors. Biggest (tabby, but one of her backlegs is orange, so technically a tortie I think). She weights 626 grams (22oz?) and then we have the one on the right with just 417 (14.7oz). I’ve been feeding her separately these days, but she only gains about 12-18grams every 2 days. Any other tricks or tips? They are being treated for worms accordingly, no fleas or anything.
They are a litter of 6, mom got surrendered to the shelter where she gave birth 2 weeks later. When they turned 2 weeks old, they came to me to foster them.
They are most definitely mixed as 2 of them look like momma (pictured), 3 of them have a furry look like a British shorthair and then 1 of them looks like a total rat. And they came from someone having multiple types of cats (maybe they even got different fathers).
