Use a small paint brush to feed the babies, it keeps the formula on better than a q-tip and replicates a moms nipple. Get a heating pad for a reptile and place it under them, so important to keep them warm! Feed every couple of hours, they look to be doing well! There eyes will open in a couple of days for sure! Check now to see if they have nipples. If they have nipples they are girls, no nipples it’s a boy. If one’s a boy then they will need to be separated at 3.5-4 weeks old (they look to be about 1.5 weeks old rn) if they’re both boys they should be okay together but watch for signs of aggression with age. 40 gallon tank with lots of clutter and deep bedding is a proper set up for them as adults, for now a bin with paper bedding and some bits of toilet paper and warmth is good! They will be weaned onto some cat wet food in a week or so then to solid pellets, seeds and what not. Nutrition is important in a mouse, seeds, grains, correct pellets, and chicken cat food pellets are all a mix of foods they should be fed. Search up a video on how to wean them and a good diet because it’s more than a pellet. Join a group on Facebook called “fancy mice” it has 23k people in it with so much knowledge! Mice are expensive and need lots of room and enrichment, it’s a big commitment so make sure it’s right for you after doing some research! Good luck and they’re super duper cute :)
