If your cat is hiding and you can't seem to get them out, there are a few things you can try. First, try to make their environment as appealing as possible. This means putting out fresh food and water, as well as providing some toys or scratching posts. You can also try using a Feliway diffuser, which emits calming pheromones that can help reduce stress. If your cat is still hiding, you may need to give them some time to adjust to their new surroundings. Once they feel more comfortable, they should start to come out on their own.
