1. Ignore the cats under the bed and leave: When cats feel stressed or scared, they may hide under the bed. If your cat refuses to come out under the bed, the best thing to do at this time is to do nothing, because it takes more time for a cat trying to adapt to its new home to feel safe. You can leave the room, and the cat may follow you in a few minutes. It is also a good idea to close the door behind you and leave, so that the cat can feel territorial in the room alone.
2. Reduce the noise around the room: High decibel noise is terrible for cats. If you feel nervous and at a loss, hiding under the bed, you can relax by consciously reducing the noise. Keep your voice down and keep children and other pets away from the room until the cat is comfortable enough to come out from under the bed.
3. Try calling your cat's name: If your cat is no stranger to your home and you are not sure of any reason why it feels anxious or stressed, it is feasible to call it out. This method works best if the cat associates its cry with food or snacks.
4. Seduce with snacks such as cat strips: In some cases, just pretend to gently open the cat can or squeeze the cat snack bag to make a sound, and your cat will quietly walk to the sound source. If the sound of eating is not enough to lure it out, then pour out the snack and put it by the bed, and then wait for it to come out quietly in the corner.
5. Place toys beside the bed: Does your cat have any toys that she likes very much? You can try to draw the toy out from under the bed and put it where it won't miss it. Toys that make noise are usually the most effective because cats can concentrate better.
If all the above methods fail, or if the cat stays under the bed for too long, it is best to consult a veterinarian or an animal behavior expert for more professional advice and help.
