Sounds good! Just supervise them when they are out of the box. I suggest you limit them to one room for a few weeks, like your bedroom. Give them some cat toys eventually, like little balls and play mice.
They black ones not wanting to eat the kmr anymore lile she'll eat alittle but idk if she wants different food because shes not sick at all o:? What can i feed them the other one still wants the bottle
What kind of cat food was it? You can mix the kmr with wet and dry food to make a mush. It is easier for the kittens to eat. Try offering it on the tip of your finger at first and lead the kitten to the dish. It should be on a plate or other flat item.
