How do I choose it?
Once you have identified the cattery, or the catteries, start asking yourself the important questions: what is my lifestyle? How many hours do I spend at home? How many hours would the cat be alone? What is my family like? Who will mainly take care of the cat? And so on.
You might find out that two kittens are the right choice for you, because Maine Coons suffer too much from loneliness and you should not leave them alone for too many hours every day. Or you may decide to prefer a female who, as an adult, will have a smaller "size". Or with small children at home you may decide to take home the kitten at 4 or 5 months, when it will be more capable of handling the relationship with the little humans and to control the "retractability" of his claws.
What for us it is the last thing to evaluate is the color even though we know it's a lost battle. Whichever color you prefer, ask the breeder to tell you about the character of kittens. Some things can be seen immediately because every kitten has traits of the personalities that you see from a very young age. There is always the Explorer, the Shy one, the little Simpering one, the Big Eater, the Cuddly one or the Clown. But know that once in your home they will adapt to your family, if there are other animals that already have the role of spoiled-child they will adapt to the new hierarchy. And if you have caught the most timid, it may be that without his little bully brother around, he will be able to be seen in all his hilarious way of being.
