Is it safe to feed my kitten with a chest cold and gastroenteritis?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I would recommend the prescription gastro-intestinal diets like Hill's i/d or Royal canin gastro-intestinal. These diets can be obtained from your Vet or a prescription from your Vet. You can blenderize it with water and syringe feed it. I would feed small amounts every few hours until the kitten is eating on it's own. Good luck!

She needs to be fed kitten food, preferably tinned. Buy some tinned kitten food from your pet doctor or a pet shop. Your kitten will need to be fed 4 times a day. Curd is not a proper feed for a kitten and could be the reason for her diarrhea. She may also need to be wormed.

Oh my goodness, Gerdou is absolutely beautiful! Yes, it is typically recommended to not feed a cat for a period of time when they are suffering from diarrhea. It allows their stomach to settle, and then a bland diet is introduced after this period of starving. For a 56 day old kitten, I wouldn't withhold food for more than 12 hours. After this time period, feed Gerdou a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. Hopefully she feels better soon, but have her seen by the vet again if the diarrhea continues on the bland diet.

What a cute kitten! Offering a meat flavored baby food may help entice him to eat. Warming his food may also allow him to smell it better which will help his appetite. Offer him small meals several times a day as his stomach is too small to eat a lot at one time at this age. Definitely have him rechecked by your veterinarian if he's not eating by tomorrow. I hope he's feeling better soon.

I would recommend that you take Arfa to your vet for a physical examination and possibly diagnostic testing, such as bloodwork, parvo testing, or x-rays. The symptoms you describe are a little vague, but could be caused by bacterial infection, viral infection (such as panleukopenia virus), intestinal parasites, intestinal obstruction, among many others. At this point, offer Arfa many different types of dry and wet cat food and even kitten milk replacer to see if you can entice her to eat. You can also syringe her water or pedialyte to try to maintain hydration, however this can worsen nausea. Many times kittens that aren't interested in eating need IV fluids to stay hydrated. Periset is an anti-nausea medication. Mega CV is an antibiotic. Polybion is a vitamin supplement.

Withhold food for so long in such a small kitten is not recommended. Diarrhea is a signs referring to a intestinal problem. It could be due to parasitic infestation (very common in kittens) dietary indiscretion, inflammatory disease, bacterial diseases or viral diseases. You could provide bland food (boiled breast chicken or white fish or gastrointestinal commercial diet) for a 24-36 but, if she continues to have diarrhea, might get dehydrated and therefore need to be checked by a veterinarian. Also if you can spot blood in the faces or if she get lethargic and not eating, or if she start vomiting, I would suggest to have her checked by your veterinarian as soon as possible. 
Good luck and post again on the forum if you need further advices. I hope my answer was helpful.

I would recommend feeding her a high calorie, soft mousse such as royal canin recovery which is highly palatable and energy dense and can be very useful to promote weight gain during recovery. Ensure she is up to date with deworming medications also
