Most cats love stability. They tend to be very sensitive to stressful or new situations and can exhibit unusual behaviour in these instances. They can start scratching furniture and door frames, for example, or urinate uncontrollably inside the house. Stressful times can include visits to the vet, a new family situation, vacations, home renovations/relocations or changes to the cat’s surroundings such as new animals inside the house or in their territory outside.
