What to do if I found a newborn kitten and its feral mom ran off?

I would keep your boy cat away from the mother and kittens. Keep him indoors for now. Put food and water under your porch for the mother. She needs a kitten formulated food to help support nursing. I'd put some blankets under there as well to help keep them warm. If you can catch them, bring them indoors into their own room with food, water, a litter box, and a nesting box. Best of luck.

Poor Kittens. You can try to clean them up and take them to her with the rest of the kittens. If she still rejects them then I would try to start bottle feeding them with KMR kitten formula. You would need to feed them every 2-3 hours. You can use a syringe or a kitten bottle. You will also need to stimulate their rear ends using a damp warm cloths after each feeding to help the pee and poop. Just be forewarned that kittens that are bottle fed from day 1 take a lot of nurturing and sometimes do not survive. I hope this helps!

It might really stress her out to be inside if she's never been inside, so I would just leave out food for her, and set up a shelter for her and her kittens. I would try to catch her after the kittens have weaned, and have her spayed. If she will allow it, I would try to handle the kittens to tame them so you can find them homes. I hope this helps!

Set up a secure location for mom and babies that is sheltered from the elements and predators until you can get them to a rescue or shelter unless you intend to take responsibility for them. Offer her food and water, kitten food ideally for her, as much as she wants. Keep an eye on them but I wouldn't try to remove the straw or untangle them, Mom may take care of that herself.

I would start supplementing the kitten with kitten formula fed out of a syringe or kitten bottle every 3-4 hours. Some times the mom will abandon her kitten but sometimes she will come back. I would try to supplement for now just so the kitten won't have any issues. I hope this helps.

Oh no. That isn't good. Cats are very unpredictable; therefore, I would air on he side of caution and feed the kittens if need be. If the kittens are less than 2 weeks of age you want to make sure they are also kept warm (but don't overheart) and I would recommend wearing gloves when handling them to avoid masking their scent, which can lead to mama cat rejecting them when she returns. It is a foreign place for her so she has an increased likelihood of getting lost or injured while outdoors. You can try to go searching for the Mama cat as well. Take a can of tuna with you to see if you can entice her to return. Also leave a way for mama cat to easily enter the house, if you can, just in case she returns and no one notices. I hope she does come back. Wishing you all the best!

Hi, a lot of kittens die because of catching viruses so as much as you protect them and make sure they are ok, if there are unvaccinated cats roaming and mum is also not vaccinated, the risk is high. Hope these kittens do well and that they can find a loving home in the future, you could try to contact a charity organisation that might help with spaying the queen afterwards and taking carol the kittens.
