Cats can suffer from depression, caused by stressors like environmental changes, loss of companions, lack of interaction, physical illness, unmet estrus needs, inherent traits, aging, trace element deficiency or past trauma.

Common symptoms include behavioral changes (quietness, hiding, irritability), decreased appetite, sleep disturbances, self-neglect, sound sensitivity and social withdrawal.

In summary, addressing cat depression requires identifying and addressing the underlying causes, such as improving companionship, stabilizing the environment, and addressing physical health issues. For severe or persistent cases, consult a vet for professional diagnosis and treatment.
