Mixed Breed Cat Highlights

  • Kittens and cats of unknown lineage are commonly referred to as Mixed Breed or Domestic cats , further refined into categories based on length of fur: Domestic shorthairs, Domestic medium hairs, and Domestic longhairs.

  • Just because a Domestic or mixed breed cat doesn’t have an official pedigree doesn’t mean you can’t show them! The International Cat Association (TICA) allows cat owners to show their non-pedigreed cat, with judging based on condition, beauty, and “show presence.” The World Cat Federation and the International Feline Federation allow housecats to compete in shows as well.

  • Mixed breed cats are the most popular cat in the United States and are a good choice for new cat owners. However, Domestic Medium-hairs are less common than the Domestic Shorthair and Domestic Longhair type cats.

  • The long hair in mixed-breed domestic cats is due to a recessive mutated gene, thought to have surfaced when cats needed warmer coats in the cooler European climates, around the 15th century.

Color Patterns of the Mixed-Breed Cat

Mixed breed cats have unknown mixed origins. As such, they can be found in any color, color combination, or pattern that is seen in other cat breeds, from Tabby to Tuxedo to Tortoiseshell and beyond!

Most often, their coloring and look trend toward the most common coloring and body style of other pedigreed cats in their geographical area. Mixed breed cats in Asia quite often have Siamese coloring, while mixed breed cats in the United States and the United Kingdom have a larger, sturdier body like the popular Shorthairs.

Unique Personality

The mixed-breed cat varies in temperament and personality, depending on its genetics and learning experiences. You’ll find all “types” of these domestic cats, which means there’s some kitty for everyone! In fact, they’re often the first cat for many owners, due to their prevalence in shelters and rescues. When choosing a mixed-breed kitten or adult cat, make sure to look for a companion that fits in with your lifestyle.

Preferred Lifestyle

Energy Level

Domestic mixed-breed cats have varied lifestyle preferences. Some cats are content to lounge around with their human guardians with occasional short play sessions, some cats are independent and self-entertaining, and others are highly active, intelligent and require constant physical and mental stimulation. If you have a particular lifestyle you’d like to share with your furry friend, consider adopting an adult cat. Since they’ve already grown into their personalities, you can get a better sense of the lifestyle they’ll need. Kittens (as a general guideline) tend to be active and playful, but may mellow out or maintain their energy level as they get older - you never know what you’re going to end up with when you bring home a kitten! That’s part of the fun.

History of the Mixed Breed Cat

Mixed breed cats can be found all over the world, as they are simply cats of a long and mixed heritage. Throughout history, they’ve acted as workers and companions to their families. Arriving in America aboard the ships of the early settlers, including the Mayflower, mixed breed cats played an important role in the new world. They may have started out keeping rodents at bay for pioneers and shopkeepers but soon became a popular family pet. According to the American Veterinary Medical Association’s report in 2018, 25% of American households include a cat. The Domestic will no doubt continue to thrive as an important part of pet culture.

Plays Well with Others?

Depending on your cat’s personality, they may get along well (or not) with other kittens, adult cats, household pets, and people. It’s always best to introduce your cat to a potential new friend slowly, giving them a choice whether or not to interact, and providing positive reinforcement for positive interactions. Particular care should be taken when introducing cats to each other, as most cats require time to get to know a new feline companion. Introductions that are rushed can result in fighting or injuries, undesirable behaviors (such as house-soiling), and stress for both humans and animals.

Exercise Requirements

Domestic cats need enough exercise to stay healthy and trim, as well as prevent unwanted behavior problems. Provide them with sufficient playtime, areas to climb, and encourage them to follow you around the house (or leash train them for outside walks) to get their steps in every day.

Mental Enrichment Needs

All cats require mental enrichment to keep their minds sharp and active. Boredom can cause stress, which results in behavior issues. To keep your kitty from getting bored, make sure you provide them with plenty of toys, rotated regularly, to keep them novel and exciting; plenty of perching places to climb and explore; cozy nooks in which to take naps; windows from which to watch wildlife; play (using an interactive wand toy) providing an outlet for their instinctive predatory behaviors; and puzzle-solving opportunities (such as food puzzles). Depending on how inquisitive, motivated, and intelligent your cat is, you might also consider clicker-training tricks and commands.

Common Behavioral Issues

While many mixed breed cats don’t exhibit behavior issues, they can crop up if cat guardians aren’t meeting the needs of their cat. Mostly commonly are house-soiling (especially if appropriate litterbox setups are not provided and maintained); inter-cat aggression (if a slow-introduction process is not followed); and destructive behavior such as scratching furniture, knocking over objects, and counter-surfing (particularly if ways to alleviate boredom are not provided). The potential for encountering these problems can be minimized or avoided by making sure your cats’ needs are being met. This means an appropriate place for elimination, territorial security, mental and physical exercise, and social interaction. Cats are also known to exhibit behavioral issues or changes if they’re experiencing pain, discomfort or medical problems. So it’s important to manage your kitty’s health with regular visits to the veterinarian.

Fun Activities the Mixed Breed Cat Enjoys

Mixed breed cats have a wide variety of preferences when it comes to fun activities. If your cat shows signs of fear, stress, or anxiety, discontinue the activity; start off small, and encourage the exploration of new objects and activities using positive reinforcement (treats, petting, praise, play, etc. - anything your cat enjoys). Have fun together while you try new things!

  • Food puzzles of all difficulty levels. Start easy, and with a high-value treat. When your kitten gets the hang of things, increase the difficulty level and perhaps mix other food in with the treats. Many cats are even fed their meals using food puzzles and puzzle feeders!

  • Play sessions using an interactive wand toy are a MUST to keep your cat physically and mentally healthy. Use a long wand with interchangeable lures that resemble natural prey items - birds, rodents, snakes/lizards, and bugs. Some cats have preferences for certain types of prey, so don’t be afraid to switch lures to keep things exciting.

  • Self-play toys such as small mice or balls that can be batted around. Even crumpled up pieces of paper and aluminum foil balls can be fun! But make sure you keep a close eye on playtime so toys don’t turn into snacks. Some cats (especially young kittens) will chew and can ingest things they shouldn’t. And don’t forget to rotate toys regularly to ensure that your cats don’t get bored.

  • Vertical space: provide plenty of places for your cats to explore - cat trees, perches, and shelves. Keep kitty safe by securing these landing and launching pads to avoid falling and crushing injuries.

  • Clicker-training can be a fun activity for smart cats. Try trick-training (commands like sit, roll-over, stationing, high-fives, etc.) or even building agility courses for cats to run through.

  • If your cat enjoys the outdoors, give them a way to safely get out of the home by taking walks in a pet-stroller, teaching them to take walks with you wearing a harness/leash, or even building an enclosed catio.
  • Cat TV - Play videos of wildlife made specifically for cats that feature birds, squirrels, and other animals. Better yet, place bird and squirrel feeders outside of a window from which your cat can enjoy a live show.


Never leave your cat alone near an open window that doesn't have a secure screen. If it's on the first floor, your cat can get out of the house and get injured, lost or any of the other possible problems that outdoor cats face on a daily basis. If the window is on the second floor or above your cat is at risk of suffering from severe injuries of "high-rise syndrome," and you don't even need to live in a true high-rise building. The injuries of "high-rise syndrome" tend to be worst in falls from between the 2nd and 7th floors!

  • Heated cat beds will be appreciated in colder months, particularly for older cats (or any aged cat that has arthritis).

  • Make sure to provide cozy escapes - boxes, bags (with handles removed), and cubbies can give cats privacy during nap times, or just a refuge from the dog or small child in the family.

  • Let your cats explore the packing paper that comes in delivered boxes - just throw a length of the crumply paper on the ground and cats will pounce, dive, and hide in it. You can also add catnip to get the party started!

Coat Type

Mixed-breed cats can have a thick, double coat of short length (less than 1 inch long), medium length (1 to 2 inches long), or long length (more than 2 inches long).

Shedding Level

Grooming Requirements

  • Low Maintenance
  • Weekly Brushing
  • Seasonal

All mixed-breed cats need regular maintenance to keep their coats healthy. Weekly brushing (more during seasonal shedding periods) will help prevent matting and furballs in short and medium hair lengths, while daily brushing and more intensive grooming is needed for long-coated domestics. While most are quite capable of keeping themselves clean, sometimes a bath is in order. Like all cats, the mixed breed cat requires regular nail trimming and teeth brushing to stay happy and healthy.
