Maine Coon: everything about the breed
Originally from Maine (USA), the Maine Coon is a natural breed that adapted to harsh winters with dense fur, plumed tail and large paws that work like snowshoes. Known as the 'gentle dog' among cats for its docility and following owners around the house. Can grow up to 1 meter long (nose to tail).
Unique physical features
- Long plumed tail (30-40cm) used as blanket
- Ear tufts (lynx tips) for thermal insulation
- Large paws with tufts between toes
- Semi-long water-resistant coat
- Loves water — many play with running faucets
Health: essential monitoring

| Hip dysplasia | 20% of breed | X-ray after age 1 |
| Spinal muscular atrophy | Genetic | DNA test before buying |
| Polycystic kidney disease | Rare | Ultrasound every 2 years |
| Obesity | Common | Weighed food, regular activity |

Breed health screening: real-world data from PawPeds
PawPeds is a European pedigree and feline health database where breeders and owners register veterinary screening results (echocardiograms, genetic tests). The figures below come from this breed's real records in the database — something generic breed pages never show.
Honest reading: participation is voluntary, so it skews toward health-engaged breeders, and the result does not predict your cat. Two practical uses: knowing which screening this breed genuinely needs (ask for parents' results when buying a kitten) and sizing the recorded prevalence.

Four years of growing: the big kitten that takes its time becoming a giant
Most cats finish growing in their first year. The Maine Coon doesn't: the breed matures between 3 and 5 years, and it is common for a second-year owner to wonder if they got a regular cat. The final numbers explain the giant reputation: males reach 6-8 kg (some above that), females 4-6 kg, and nose-to-tail it is easy to top one meter.
A long growth period calls for large-breed kitten food for longer, with controlled calcium and phosphorus so the joints keep up with the skeleton. And weight must be measured: the 'chonky Maine Coon' joke repeats in every clinic, and each extra kilo taxes the hips, one of the joints this breed already tends to overload.
Four real demands of the breed (beyond the cuteness)
Semi-long coat with a dense undercoat: brushing two to three times a week prevents mats under the arms and along the britches, and the spring shed requires daily brushing. Choose a wide slicker brush, not a de-shedding rake.
Heart: HCM is the breed's disease. An adult echocardiogram and a pedigree with the parents' results are the real filters — the PawPeds database on this page shows the scale of screening serious breeders do. A tall, sturdy cat tree (an 8 kg cat needs a stable base), running water that the breed loves, and screened windows: a Maine Coon is too curious to trust a flimsy screen.
