We have five cats, four adults and a kitten. Other cats eat well but this one is just keeping slim lean thin like it was a fashion model on a catwalk. She is a Maine coon and just got two years old this month, and I'm getting anxious about her weight. She is a little over 90 cm (3 feet) including tail, and weighs about 3,5 kg (under 8 lb). Wikipedia says an adult female Maine coon should be 10 to 15 lb.
She eats dry food and wet food, just like the others, but ever so small amounts of it at a time. We have dry food on constant offer and wet food two or three times a day. During the first 18 months I told myself that she is just busy growing up, as these Maine coons are slow to build up their body, so she just don't get body mass until she has reached her full size. But our other cats are (slightly) younger than this one, and they're looking like already at their full adult size. So for the last half a year I've been wondering if she is allright.
Half a year ago she was at a vet to get her vaccines and the vet said something about her possibly being in heat every so often, and that consumes a lot of energy. The vet said our cat sure is a bit too lean, but it should change soon after spaying. I don't know, we have plans to let her have one set of kittens before doing that. And we've been waiting for her to grow up before introducing her to a tom. (That's part of it why we now have the male kitten..)
After that talk with the vet I've started buying Royal Canin Exigent 33 Aromatic Attraction food for fussy cats. The slim cat seems to like it, but our other cats love it. So our other cats are gaining weight perhaps a bit too merrily, only because I'm trying to fatten this one.
To sum it up: a two year old female Maine coon is ever so slim, even though she does eat. How slim is normal for this breed? Am I worried for nothing, and if not, what can I do?
