You must know that during relocation, it is not only you who is in need of serious adjustments. Your pet too needs to do this, especially if it is a four-legged creature like cats and dogs. You will know if they are not adjusted if they start behaving abnormally. They can even have weird reactions to certain things. If this goes on and on, you might have to help them adjust. It is your responsibility to do various interventions to help them feel comfortable to the new place or else your own comfort and convenience would be at risk as well.
