Hello everyone! New poster here, I'm concerned about a rescue cat we adopted yesterday. We actually adopted 2 cats who are brother and sister, which we named Bobby and Luna, both are shorthair and Bobby is a tabby and Luna is a black cat. They're pur first cats but my partners parents have always had cats since he was little. We don't have any kids or any "free-roaming" pets. When we first got them we confirmed them to one room for a few hours before leaving the door open, I tempted them with some treats and they started to explore the house. Within only 10mins of the treats Luna was completely comfortable, head bumping and licking our ears as well as talking to us. Bobby went straight under our bed all night. Next morning Bobby had confined himself in our downstairs bathroom. As he hasn't moved all day today we moved a food and water bowl in there with him so he didn't go hungry or thirsty. There was a litter tray in the kitchen not far away however he we did put a towel on be bathroom floor cause at least we can wash that. He peed on the towel and has pooed in the corner! We've tempted him with cooked chicken and dreamies and he has come out of his hiding place to grab the treats then hidden. He has eaten some of the normal cat food we've left for him and I think he's had some of the water too. My partner has used one of those chase toys with him and he did engage for a little while before hiding. Note: they're both also underweight. I'm being supplied with special cat food for them by the charity.
