If your cat is scared, it's likely they will want to hide away until they feel safe again. How long this takes depends on the individual cat and the situation they are in. If there are no other cats around to act as a support system, your scared kitty may take longer to come out of hiding. However, if another calm and friendly cat is present, your frightened feline may only stay hidden for a short while before investigating their surroundings further. Ultimately, it is up to the cat to decide when they feel safe enough to leave their hiding spot.
