These are indoor cats. Tourmaline has been introduced to her other two cats and now she's trying to find a way of making a feeding station for the three. The other two have been together for over a year so they are buddies now but Tourmaline is just a friendly acquaintance. Is there a way for her to make a feeding station, inside, without any of the cats feeling like they're being replaced. Sorry I'm not really good at explaining what is needed. Hope someone reading this knows. Thanks.
