Are Norwegian Forest Cats Prone to Obesity?

One of the most important reasons to keep an eye on your cat’s weight over time is to ensure they stay healthy. Obesity is a serious problem for any pet, that can be very damaging to their health.

Norwegian Forest cats are, unfortunately, prone to obesity, weight issues, and joint problems because of their large size. They need to consume a lot of food to sustain themselves, but if this is not managed properly, they can become overweight.

Obese or overweight Norwegian Forest cats are at greater risk of many different health problems, including:

  • Diabetes
  • Liver Disease
  • Arthritis
  • Urinary Issues
  • Joint Problems
  • Pancreatitis
  • Gastrointestinal Disease
  • Breathing Problems
  • Skin Conditions
  • Cancer

At the end of the day, an overweight cat is sadly not likely to live as long as a cat that is a healthy weight.

How Do You Keep Your Norwegian Forest Cat a Healthy Weight?

You need to keep two things in mind when it comes to your cat’s weight: diet and exercise. 

They should be eating healthy, high-quality cat food that is rich in protein, and you have to ensure that you are not giving them too much! These cats do need to eat a bit more than your average breed, but you don’t want to overfeed them.

When it comes to exercise, your Norwegian Forest cat will need to stay active and keep moving throughout the day. These are cats that love to play and explore, so they should have a good amount of room to move around in. There are many different interactive toys that are great for entertainment as well as exercise.

Norwegian Forest cats are particularly fond of climbing, so they will probably try to get on top of all of your bookshelves and cupboards. It’s a good way for them to stay fit, but you might want to invest in a cat tower, so they aren’t always on your furniture.
