A study has found that cats exhibit signs of grief when a fellow pet dies, with some reports suggesting this behavior is not limited to the death of another cat, but may also occur when a dog dies. The research implies that cats may be capable of experiencing grief, although the extent of this phenomenon is still being explored. The study's findings have been interpreted in various ways, with some outlets suggesting that cats may also grieve the loss of humans, while others focus on the death of fellow pets.
