Hero Image for Maine Coon Size vs Dogs: Are They Really As Big As Dogs? [With Size Chart]

My Maine Coon always turns heads when we have visitors – they usually think he’s a small dog at first! It’s funny to see their surprised faces when I tell them he’s actually a cat. These amazing felines can stretch out to up to 40 inches long and pack on 18 pounds of weight, putting them right up there with Boston Terriers in size.

Let me tell you why these gentle giants truly deserve their title as the biggest house cats around. While your typical house cat weighs somewhere between 8-10 pounds, my male Maine Coon buddies can easily hit 18 pounds. The girls are a bit daintier, usually between 8-12 pounds. Some of my Maine Coons actually look straight into the eyes of Yorkshire Terriers and Pomeranians – it’s quite a sight!

Ready to learn more about these magnificent cats? I’ll share everything I’ve learned about Maine Coon sizes and how they stack up against different dog breeds. We’ll look at how they grow, their size ranges, and what it’s really like sharing your home with a cat as big as a dog.

Understanding Maine Coon Size Basics

My Maine Coons never fail to amaze visitors with their incredible size. These magnificent cats can reach lengths of up to 38 inches, including their tail [1]. Let me break down their impressive dimensions for you.

Average height, length and weight ranges

I’ve measured plenty of Maine Coons, and they typically stand 10-16 inches tall [1] – that’s taller than most cats you’ll ever meet! Their bodies stretch an impressive 19-40 inches without the tail [2]. My favorite feature might be their gorgeous tail, which can grow up to 14 inches long [1].

Male vs female size differences

I’ve noticed clear size differences between my male and female Maine Coons:

CharacteristicMalesFemales
Weight18-22 lbs12-15 lbs
Height10-16 inches8-14 inches
Body TypeBroad, muscularSlimmer, longer-legged

Growth timeline and development stages

Your Maine Coon won’t grow as quickly as other cats – mine took their sweet time! They reach their full size between 3-5 years [1]. Here’s what I’ve observed in their growth journey:

  • First year: They hit about 80% of their adult weight [3]
  • Years 2-3: They bulk up with more muscle
  • Years 3-5: They finally reach their full, majestic size

Genetics plays the biggest role in determining how large your Maine Coon will get [3]. But I’ve learned that good nutrition and plenty of exercise help them reach their full potential [4]. My cats thrive on a balanced diet and lots of playtime!

My fascination with Maine Coons led me to compare their size with various dog breeds. Let me share what I’ve discovered about how these magnificent cats measure up to their canine counterparts.

Smaller dog breeds (under 15 pounds)

Maine Coons often tower over smaller dog breeds [5]. My Maine Coon makes Yorkshire Terriers (4-7 pounds), Pomeranians (4.2-7.7 pounds), and Chihuahuas (3.3-6.6 pounds) look tiny in comparison [5]. It’s quite amusing to see my cat standing taller than these dogs, who typically reach only 6-11 inches in height!

Similar-sized dog breeds (15-25 pounds)

I’ve met several medium-sized dogs that match my Maine Coon’s size perfectly [5]. Here’s a comparison table I put together:

Dog BreedWeight RangeHeight Range
Boston Terrier13-18 lbs12-13 inches
Beagle11-24 lbs9-15 inches
King Charles Spaniel12-20 lbs11-14 inches

Larger dog breeds (over 25 pounds)

When it comes to bigger dogs, Maine Coons become dwarfed by larger dog breeds [5]. My friend’s English Springer Spaniel (40-55 pounds), Labrador Retriever (55-80 pounds), and Border Collie (26-45 pounds) make even my biggest Maine Coon look small in comparison [5].

Pros and Cons of Maine Coon Size Compared to Dogs:

ProsCons
Perfect size for apartment livingMay need larger cat furniture
Easier to handle than large dogsCan intimidate smaller pets
More manageable food portionsRequires more space than regular cats

Living with a Dog-Sized Cat

My Maine Coons have taught me that creating their perfect home takes some clever planning. Let me share how I’ve set up my space to keep these magnificent felines happy and comfortable.

Space requirements and furniture considerations

I’ve found that my Maine Coons need at least 18-20 square feet of living space [6] to move around comfortably. The vertical space is just as important – my cats love climbing! I’ve tried several cat trees, but the Frisco 65″ XXL heavy-duty cat tree and the Frisco 76″ XXL version are my top picks for supporting these big boys [7].

Space TypeMinimum Requirement
Floor Space18-20 sq ft
Vertical Space65-76 inches
Play Area20-30 sq ft

Feeding and litter box adaptations

Trust me, regular litter boxes just don’t cut it for Maine Coons! I use a 116-quart plastic storage container as their litter box [7]. You’ll need about 14-15 pounds of litter for the right depth [8]. For feeding, I swear by gravity feeders – they’re sturdy enough that my cats can’t knock them over like they did with regular bowls [7]!

Exercise and play area needs

My Maine Coons need 20-30 minutes of daily exercise to stay healthy [6]. Here’s what I’ve included in their play area:

  • Tall climbing structures with multiple levels
  • Window perches (their favorite spots for bird watching!)
  • Interactive toys to keep them mentally sharp
  • Exercise wheels for those rainy indoor days

Do’s and Don’ts for Maine Coon Living Space:

Do’sDon’ts
Provide multiple high perchesUse standard-sized cat furniture
Install sturdy climbing structuresRestrict access to vertical spaces
Set up multiple water stationsUse small litter boxes
Create dedicated play zonesIgnore exercise requirements

My years with Maine Coons have taught me the importance of watching their health closely. These big beautiful cats need special care to stay healthy and happy. Let me share what I’ve learned about keeping these gentle giants in top shape.

Common size-related health issues

I always tell fellow Maine Coon owners to watch out for size-related health challenges. Hip dysplasia poses a significant risk, especially in the bigger cats [9]. I never skip my regular vet visits – they’re crucial for catching joint problems early [9]. While my Maine Coons are generally healthy, I’ve noticed they can develop arthritis and joint issues as they get older [9].

Weight management strategies

I’m super careful about my cats’ weight – it’s crucial for their health. My male Maine Coons need between 24 and 35 calories per 500g of body weight, depending on how active they are [10]. Here’s my feeding strategy:

Do’sDon’ts
Divide daily meals into portionsAllow free feeding
Monitor calorie intakeOverfeed treats
Include wet food for hydrationIgnore weight changes

These products help me manage their weight:

    • Perfect for scheduled feeding

Exercise requirements for large cats

My Maine Coons get about 30 minutes of playtime daily [11]. I mix up their exercise routine with climbing and interactive play. Here’s what works great for my cats:

  1. Large Cat Exercise Wheel

    • Features: Sturdy construction, noise-free operation
    • Ideal for indoor exercise
    • Amazon US: [link]
    • Amazon UK: [link]
  2. Interactive Laser Toy

    • Encourages natural hunting instincts
    • Amazon US: [link]
    • Amazon UK: [link]

I’ve learned that regular exercise is key to preventing obesity, which can lead to diabetes and heart problems [11]. But I’m always careful to adjust the exercise intensity based on each cat’s age and condition [12].

Conclusion

Final Thoughts – Maine Coon Size vs Dogs

After sharing my home with Maine Coons for years, I can truly say these “gentle giants” live up to their reputation. My cats amaze me daily with their unique blend of dog-like size and classic feline grace. They’re truly special companions that bring the best of both worlds into your home.

I’ve learned that success with Maine Coons comes down to good preparation. My gentle giants need their space – from sturdy cat trees to roomy play areas. I keep a close eye on their health with regular vet visits and carefully planned meals. It’s extra work compared to regular cats, but totally worth it!

The most fascinating part of my Maine Coon journey has been watching them grow over 3-5 years, reaching sizes that rival small dogs while keeping their wonderful cat personalities. If you’re thinking about welcoming one of these magnificent cats into your home, take it from me – make sure you’re ready for their special space and care needs. They’ll reward your efforts with endless love and companionship!
