Give your cat a nose-to-tail exam, making sure that its ears and teeth are clean and odorless, fur is free of parasites, skin is lump- and bump-free, and weight has remained stable.read more
When a cat who has previously been playful suddenly doesn’t feel like frolicking, there could be cause for concern, says Dr. Jules Benson, VP of Veterinary Services at Petplan pet insurance. While dogs are usually fairly good at letting us know they have a problem, cats tend to be more “private” in their expressions of illness. Since cats evolved as largely solitary, territorial animals, they tend to hide signs of pain and discomfort, and often the first signs pet parents see are persistent changes in behavior, including sleeping more or eating less. It might be easy to surmise that he’s become bored by his toys or he’s just getting older (or lazier!), but these changes could actually signify that something is wrong. A visit to the veterinarian would be the best way to rule out any health concerns that might be bothering your feline friend.
Of course if your cat’s physical comes up clean, you’ll have to consider other things. Have there been any changes to the family schedule that might be leaving him out of sorts? Have you introduced any new family members, either two- or four-footed? Is there any construction occurring in the home, or strangers in and out of the house? It could even be something as seemingly minor as re-arranging the furniture or moving his litter box. So think carefully about changes to his environment that might be putting him off his game, and talk to your vet about how to help get him back into it.
