Hi everyone, I am new here and I am in desperate need of some advice. Last Wednesday I took in two orphaned kittens from my neighbor, she had five but I could only afford to take two. She came upon them from a friend and didn't know how old they were or any other information about the mother etc. I am guessing they were about 3 weeks, very wobbly walking, ears standing up, starting to attempt to play, starting to potty on their own but not all the time. The black one started eating with no problems, very healthy appetite: the grey one was very weak and sick looking from the start, I had to drop the formula in its mouth every 15 minutes but it eventually gained an appetite and is now eating good. They have had increases in strength and appetites, they are walking almost without wobbling and even showed a good amount of interest when I introduced them to some canned kitten food today. My concerns are with the black kitten, Tarzan, last night and today he refuses to eat. I am feeding them with a dropper and Tarzan usually sucks down 3-4 droppers full of formula in one feeding but I can't get him to even take a half of one since last night. When I woke up today his belly was still very plump and a little hard from yesterday so I stimulated him until he went potty and his belly went back to normal. The later in the day it gets the more he seems to be regressing with his walking, he seems to be getting clumsy instead of better at it. I do not have any experience with orphaned kittens so I have no idea what to do or expect or anything.
