Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed

I have a foster kitten who I think is maybe 3 weeks old who is nursing off my momma cat that's not her momma. My question is will she get enough milk from her? She looks so frail and tiny. Should I take her to the vet?

She does look underweight, when was the cat she is nursing from pregnant? the milk will be sufficient only if the cat she is nursing from gave birth in the past few weeks, if not then you must feed her with kitten milk replacer which you can get from the pet shop.
