Does a cat suffer from psychiatric illness?

Anxiety is a widespread problem in cats. Its manifestations cover a wide range of signs, from agitation and withdrawal to altered eating or sleeping habits, destructive tendencies and excessive grooming. When cats are anxious, they may also claw in unusual patterns or change their litter box habits, often as a result of increased stress. The causes of this condition can be diverse, encompassing both physical and medical factors. Indeed, a cat faced with physical discomfort may develop anxiety as a result. This complex situation makes it difficult for veterinarians to establish a precise diagnosis, taking into account not only relational and environmental influences, but also physiological aspects.

Depression in cats:

While depression in cats remains under-researched, its reality should not be overlooked. Feline signs of depression include reduced activity, disinterest in play and daily interaction, loss of appetite and excessive sleeping. They may gain weight as a result of passivity or, conversely, lose weight when they sulk. Remarkably, these symptoms mirror those experienced by humans in a similar psychological state.

In an article dated September 22, 2021 entitled “Is cat depression real?”, American veterinary behaviorist Wailani Sung examines the potential triggers of this condition in cats: the loss of a family member (human or animal), a change of residence, changes in household schedules resulting in prolonged absence of their human companions, and physical changes.

Sadly, this condition remains largely under-diagnosed in cats due to its subtle nature, often confused with other conditions. As cats are unable to communicate verbally, it can be difficult to assess their emotional well-being. Nonetheless, it is essential to support cats facing depression, as it can have devastating consequences, culminating in self-abandonment and deterioration.
