At some level, animals seem to understand the concept of death. From elephants who grieve for the loss of a herd member to whales who won't leave their dead babies behind, many species react to death in much the same way that people do.
It is generally assumed that humans are the only animals who can possess a concept of death. However, the ubiquity of death in nature and the evolutionary advantages that would come with an understanding of death provide two prima facie reasons for doubting this assumption.
It is thought that animals, and especially cats, can detect by smell the chemical changes that occur in an animal or human body immediately before death. They have also been known to respond to the physical and emotional needs of the animal or person that is passing away.
Because mourning is not limited to big-brained cetaceans (whales and dolphins) or primates – scientists have documented some form of “death response” in seals, manatees, dingoes, horses, dogs, housecats, and more.
“I believe we are now justified in thinking that chimpanzees have some kind of awareness of death,” says psychologist James Anderson of Scotland's University of Stirling, who has been studying chimp responses to the dying.
They provide comfort not just in death but also in other difficult times, whether it's depression, job loss or a move across country. Dogs know when people are dying or grieving, through body language cues, smells only they can detect and other ways not yet known, experts say.
While no-one will ever know if a cat understands death, they certainly know that a fellow housemate is missing and that something has changed in the house. The owner's distress at the loss of a pet may also be communicated to the cat, adding to the confusion it may be feeling.
You will notice your cat becoming more lethargic, sedentary and refusing to move. Their weakness will be very apparent in their hind legs, and they will also sleep a great deal more than usual.
It's not unusual for dogs to grieve the loss of a person they've bonded with who is no longer present. While they might not understand the full extent of human absence, dogs do understand the emotional feeling of missing someone who's no longer a part of their daily lives.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
Animals know when they are dying. They are not afraid of death, at least not in the sense that we people are. Nearing death, they come to a place of acceptance and try to communicate that to us. Not surprisingly, because of our own grief, sadness, and distress at losing them, we may be unable to receive that message.
Although my dog may stare at me like I'm a deity, there's no evidence to suggest that non-human animals have religion. They don't worship, pray or believe in gods of any kind, but they do perform ritualistic behaviours, prompting some to speculate that animals could have a spiritual side.
Answer: Fortunately for us, dogs do not understand they are going to be put down and what happens after they are given the injection that puts them to sleep.
A growing body of scientific evidence supports the idea that nonhuman animals are aware of death, can experience grief and will sometimes mourn for or ritualize their dead.
It's been shown that dogs have uncanny abilities to detect medical issues, such as cancer, oncoming episodes of medical crisis (such as seizures), or anxiety. There is anecdotal evidence that dogs can also sense death, but how they process and perceive this information is still being debated and researched.
When a cat loses a companion, whether animal or human, she most certainly grieves and reacts to the changes in her life. Cats alter their behavior when they mourn much like people do: They may become depressed and listless. They may have a decreased appetite and decline to play.
They will only feel a needle prick, but some felines may be more sensitive to this than others. If your vet injects the euthanasia drug directly from a needle and syringe, again they may react slightly to the needle prick but will not experience any pain when the drug is being injected.
Ideally, bury your cat within the day it died or the day afterward. A prompt burial is especially important in warmer months. Unfortunately, if a cat dies in the winter a prompt burial is not always possible. The ground may be frozen over.
Conclusion. Most cats don't understand that kisses from humans are a sign of affection. A cat will surely let you know if they enjoy being kissed or not. The best ways to show your cat that you love them are to give them toys, treats, and plenty of one-on-one time.
Cats are often thought of as being independent creatures who are happy in their own company. But your cat can get lonely. Interacting with the human they love helps to enrich their lives (and yours). If your cat sleeps with you this indicates that they enjoy your company and want to spend time with you.
It appears that cats can sense human moods as well as depression. Cats are observant and intuitive, and this allows them to understand emotional cues from humans. So when you are depressed, they can sense that too. In particular, cats may come in closer proximity when their fur parents are depressed.
It can take anywhere from days to months for a cat to go through these three stages. The ASPCA study had similar findings, stating that all cats who had lost a companion returned to normal within six months.
Most experts agree that the time to get a new pet is after you have worked through your grief adequately to be able to look forward to a new pet instead of back at the recently departed one. That process could take a week or two – or many months.
