Look for signs of grieving in your cat. A change in activity is a good sign. The change may involve your cat pacing a lot in search of his lost buddy, hiding from you, acting lethargic or sleeping a lot. If your cat cries a lot and requires more affection or does the opposite and shuns affection, it can also be a sign of grief. And lastly, a lack of appetite may also signal a grieving cat.
Take your cat to be examined by a vet if you observe any of the above signs. It's best to rule out any medical issues to establish that it is, in fact, grief.
Try to stick to your cat's normal routine as much as possible. The grieving was already caused by a big change, so it's best not to compound it. For example, stick to the same feeding routine, try not to have a lot of strangers around or go on any extended trips.
Shower your cat with extra love, attention and cuddling. If your cat has a favorite toy, break it out and start playing. It's best to try and keep your cat stimulated and occupied.
How to Help a Grieving Cat
If you have a cat, you have probably wondered if cats ever grieve. Although there isn't much scientific evidence that they do--all signs point to "yes." The fact that cats form close bonds with humans and other animals only suggests that they do grieve when the bonds are cut. Cats are also so sensitive to changes in their lives, such as a new home or being kenneled, that they can suffer an emotional response similar to grieving. Here are ways to console a grieving cat.
