Life with a Maine Coon
The Maine Coon has a moderate energy level and enjoys regular play sessions. As a large cat, its adult weight typically settles at 25–45 kg, and its coat needs frequent brushing to prevent matting.
In terms of coat care day to day, this breed sheds quite heavily, so expect hair on furniture. Around the home, the Maine Coon has a reputation as an excellent family cat and is typically very sociable with other animals, though every individual cat has its own personality shaped by early handling and socialisation.
This breed generally prefers cooler conditions and may need extra water and shade in summer. The tools below are pre-loaded with typical figures for the Maine Coon so you can get a quick, personalised estimate for feeding, age and cost.

Estimated UK costs
Ongoing costs (food, insurance, routine vet care, flea/worm treatment and extras) for a Maine Coon typically run to around £127–£172 a month, or roughly £21,336–£28,896 over an average 14-year lifetime, not including one-off costs like purchase price, neutering or equipment.

These figures are UK averages and will vary by region and lifestyle.
Health conditions to be aware of
Like all breeds, the Maine Coon has its own set of conditions vets keep an eye out for. Knowing about them ahead of time means you can ask the right questions, consider health screening, and choose insurance cover that suits.
- HCM
- Hip dysplasia
- Spinal muscular atrophy
A breed being prone to a condition does not mean your pet will get it. Ask your vet about screening and insurance.
