Why Cats’ Meow And Yowl At Night

Recently, I have had many complaints from people about cats who keep them up all night.  The people are desperate for help due to lack of sleep.  Here is a list of the common causes of meowing or yowling that I see broken down into two categories.  I will address treatments in my next post. 

Medical:
-Hyperthyroidism or excess thyroid hormone may cause vocalizing and hyperactivity.  This is more common in cats over 7 years of age.  
-Testicular tumors that secrete testosterone.
-Intact (not spayed or neutered) animals looking for a partner.  This is the season when love is in the air.
-Hormonal stimulation in animals that were improperly sterilized.
-Drug side effects.
-Pain especially from osteoarthritis.  I had one patient that had trouble getting into the litter box.  He would stand beside it and meow until someone put him inside.  Cutting down one side gave him pain-free access.   
-Pruritus causes by allergies or external parasites.  Fleas, bed bugs and mites tend to be more active at night. 
-Dementia and brain tumors.
-Hypertension which is often found with renal insufficiency in older cats.

Behavioral:
-Anxiety which often occurs as cats age and their senses diminish. 
-A cat that is protecting their resources or territory will make a lot of noise.  This often occurs when the resident cat sees or smells a cat outside their home.
-Boredom due to lack of behavioral enrichment.  Cats need places to rest, eat/drink, use the litter box and play.  Sometimes, we forget the need for play.  
-Lack of exercise is a huge problem for indoor cats.  Besides causing unwanted behaviors, it also leads to obesity.  As my professor taught me in veterinary school, “A tired animal doesn’t get into trouble.”
-Hyperactivity related to high carbohydrate diets.  In some ways cats are just like kids, feed them a high carbohydrate (sugar) snack and watch out.
