We started to give them “gruel” (the second step formula) when they got to be about 5 or 6 weeks. Main reason then was they were going through a bottle a piece each feeding and it was taking so long to feed them. I also had two that didn’t want to take the bottle. There was one who never did like to take the bottle…I had to cut the nibble opening extra big for her so I could just get some in her (thought we would lose her but we got lucky). I did find that once in a while one would try and just chew on the nipple. I would find the nipple was clogged and they we not getting any milk. Just clean it out and you might be good to go.
Vets are so funny, I have three that I see at our clinic. Each one has helped us out and everyone knows us now when I call. One of the receptionist actually knows my voice and asks which one are we worried about today. Luckily now at 6 months we are health and not going to the vet every week…thank goodness for multiple cat discounts.
Hopefully I can help a little since other here helped my when I was in tears and thought I had lost my mind for taking in 7 little babies…

Good luck and keep us up to date on how things are going, explosive as it may be.
