Frequently asked questions

How much does a Nebelung cost?
The Nebelung is rare, so expect limited availability and waitlists; kittens from registered breeders in the US commonly run about $1,000-$2,000. The purchase price is only the start: across a long 13-18 year life, food, litter, grooming and routine vet care typically add $12,000-$20,000 or more, and any chronic illness adds thousands on top.
Is a Nebelung just a long-haired Russian Blue?
Essentially, yes. It was developed from Russian Blue lines and shares the same blue coat, green eyes, quiet nature and reserve, with a longer, silkier coat. If you love the Russian Blue temperament but want a semi-long coat, this is the match.
Are Nebelungs good with children and guests?
They are gentle but shy and slow to trust, so they do best with older, calm children and quiet homes. They tend to hide from strangers and dislike noise and chaos. Give them time, space and retreats and they bond deeply with their chosen people.
How much grooming does a Nebelung need?
Moderate. The semi-long double coat should be brushed two to three times a week to prevent mats and reduce shedding, with a little more attention during seasonal coat changes. It is not a wash-and-go cat, but it is not high-maintenance either.
