I would syringe food him 1 ml 3 / per day-- do you have any critical care ? Herbivore or carnivore? I dont think you can get it at the pet store at least I have looked here in mine and I cant get it there only at vets --- I would give him some baby food chicken and may be mix the squash and chicken together water it down and give it to him that way - 1-1 ratio - make it watery so it comes out of the syringe easier - my husband made the end of the syringe wider by boring it open w/ a knife - you may need assistance doing it --- take the bottom lip on one side w/ the thumb and pull down to get the syringe in I used my for finger and went on on opposite side and got baby to open mouth that way - and slowly put food in so he didnt aspirate the food -
