“Cats do not present for fearful behaviors nearly as frequently as dogs, although as a species they are probably every bit as fearful. However, when faced with a fear-inducing stimulus the cat’s natural tendency is to flee, and hide. In this way they tend to deal with their fears, and not lay them at their owner’s feet as dogs do.
Chronic Dysfunction Syndrome
“The most common signs of [Chronic Dysfunction Syndrome] can be remembered by the acronym DISH: disorientation, less social interaction, altered sleep patterns, and house soiling. It’s unusual to see all four signs in an animal, and the diagnosis can be made on the basis of only one sign.
“In cats, common clinical signs include aggression against the owner, strangers, or housemates; inappropriate elimination; increased vocalization; disturbances in the sleep cycle; excessive grooming; and disorientation or confusion. Many causes of CDS exist for cats.”
[Among treatments options is melatonin, according to the article.] (“Chronic Dysfunction Syndrome Among Manageable Behavioral Problems”, American Journal of Veterinary Research, AVMA News, September 15, 2005, USA)
“… For a cat, I’d probably start with about 0.75 mg [of melatonin]. Dose to be repeated as needed up to three
times a day.” (Pet Shrink, “a veterinary practice focusing on behavioral problems,” Berlin, Massachusetts, USA)
