The kittens should be drinking KMR, just the way you are feeding them. At 4 weeks old, there are ready to be weaned but bottle feeding might still be needed if they are not eating properly yet. Orphaned kittens can be weaned earlier than their naturally raised counterparts.
Some E. coli bacteria are contagious while others are not, depending on the E. coli strain and/or the infection type. Some strains that cause gastrointestinal problems (enteropathogenic E. coli) can be transmitted person-to-person, usually by the oral/fecal route, and even indirectly by contaminated food or water.asual contact (shaking hands, kissing) will not usually transmit E. coli person to person. However, some strains of E. coli, including the diarrhea-causing enteropathogenic strains, can be contagious. Medically Reviewed by a Doctor on 6/29/2015.
Escherichia coli (E. coli) is a bacterium that is commonly found in the gut of humans and warm-blooded animals. Most strains of E. coli are harmless. Some strains however, such as enterohaemorrhagic E. coli (EHEC), can cause severe foodborne disease. It is transmitted to humans primarily through consumption of contaminated foods, such as raw or undercooked ground meat products, raw milk and contaminated raw vegetables and sprouts.
