I started fostering a kitten whose mama abandoned him and when i took him to the vet she said hed weighed about 2 weeks old but i know hes 4 weeks. Im nervous that he wont make it now. She recommened feeding him 40mls a day of kmr. Has anyone else had thid happen to them? Will he still survive and maybe just be smaller? He plays a lot and i have him on amoxicillin and i am deworming him too. Do you guys have any advive?
