Hi guys! New to this. My partner and I got a 9-week old cat (first ever pet) a few days ago. Took her to the vet yesterday to have her vaccinations and was told she was under-weight. 0.7kg, versus the 1kg that the vet expected her to be. How fast will she grow if we keep food down for her? Bought her some Whiska's kitten food, both soft and hard, and cats milk. Thanks.
