The toys that you choose for your cat must take into account the natural behavior of the species. Often the simple ones are the best and ones that offer unpredictable movement, rapid movement and high-pitched sound are likely to provide your cat with hours of entertainment.
Territorial aggression is aggression that is exhibited toward people or other animals (usually cats) that approach or reside on the pet's property. Aggression can occur toward outside cats or to cats that live in the same household, especially new cats coming into the territory.
In cats, excessive sucking and chewing, hunting and pouncing at unseen prey, running and chasing, paw shaking, freezing, excessive vocalization, self-directed aggression such as tail chasing or foot chewing, over-grooming or barbering of hair and possibly feline hyperesthesia may all be manifestations of conflict, and may become compulsive disorders in time.
Spraying is the deposition of small amounts of urine on vertical surfaces. In most cases, the spraying cat will back into the area, the tail may quiver, and with little or no crouching, will urinate.
Some cats are active at night, or are awake and raring to go very early in the morning. Since many owners are out at work or school during the day, the cat may spend the daytime hours in rest and relaxation, especially if it is the only pet in the household.
