There's a stray cat i have been feeding for awhile and six weeks ago she had kittens. My mom who lives next to me has taken the kittens into her home. We took one to the vet that was sick and got them toys cat food litter boxes.But I feel sort of bad because they keep crying to go outside. I feel like we're forcing them to be inside where they don't have as much room to explore as they did outside and the mama cats been walking around outside looking upset. I don't know what to do we want to keep them inside so they're safe and taken care of but they keep crying and trying to get out so i feel guilty keeping them indoors. Will they be ok does it just take time for them to be used to staying indoors and could they be happy permanently inside now ?
