This will cause them to lick their lips and get a taste of the food without forcing it on them. This might take several sessions for the stubborn ones. Cough.

The first thing that you have to ask yourself is are you feeding your Maine Coon mostly dry or wet foods. Cats, in general, do not drink a lot of water. Instead, they get the majority of their water content from the food that they are eating.

This is a problem if you only feed your Maine Coon dry food.

While it sounds conducive to how cats naturally eat, they like to graze throughout the day, putting a bowl down with just dry food often causes your Maine Coon to woof it down so to speak.

The telltale sign is if in your Maine Coon’s vomit there are chunks of the food that they ate. This means that your Maine Coon filled their stomach too much and didn’t even digest the food itself. Which causes a double problem.

They are not getting a lot of water content from the food, and they just lost some from the act of throwing it up.

If the recommendation from your vet is that your Maine Coon eats only dry food or you cannot get your feline to eat wet food there is a solution.

Purchase a slow eater contraption from your local store or online that fit into the food bowl and have soft prongs sticking out.

This will make your kitty have to move around the prongs to eat ensuring that they digest slowly. Also, it might be a good idea to invest in a water fountain for your Maine Coon to encourage them to drink more water.


Another vomiting issue that comes with Maine Coons is hairballs. If you are new to cats be prepared for the hunched over heaving that occurs with a long-haired cat.

This is distinctive from other vomit due to, well, the globs of hair. Standard across the board for cats, worse in our thick haired friends.

Your fur baby will continue to groom, as they should, but there are ways to prevent them from getting too many hairballs.

You should brush your Maine Coon around twice a week.

To a cat, grooming is stressful and invasive, so there are some tips to help make sure it is a positive experience for them and a less wound inflicted incident for you.


  1. Groom when they are relaxed, after eats or exercise.
  2. Do not groom when you are in a bad mood.
  3. Keep it short just 5 or 10 minutes until they are used to it.
  4. Pet your Maine Coon while grooming to make sure they are at ease.
  5. For thick haired cats make sure to get the belly (oh no) and legs first because that is where knots typically occur. Good news for Maine Coon owners since these cats don’t usually get matty hair.

Use a metal comb gently at first and then use a rubber comb to get loose hair and dead skin going back and forth on the fur.

If the experience was stressful to them, make sure to give lots of pets and love afterward to make sure they know everything is ok.
