Is she under weight?

[SaeKitty45]

I used Wii fit to Weigh my cat (it's made to do it, apparently)
It's fairly accurate.

Anyway, my kitty, Meili is quite long.
She weight about 6.5 pounds, I think. She is pretty light.

That sounded low to me, and I don't want to get accused of under feeding when I take her to the vet.
But she has food available at all times, she's just very active.

Does she sound underweight? If you look af her from above, you can see where her back legs are "sticking out" as compared to her stomach/mid section. Her ribs don't show, she's muscley, you can see her muscles when she's walking, or standing on her back legs looking out the window...

Do you think she sounds too thin?

She doesn't look underweight in that photo, although it isn't in the best position to tell.  As Diva said, cats can be very different in bone structure and other factors related to "normal" weight.  I have a small boned adult cat who weighs about 7 pounds and another larger boned adult cat who weighs about 10 pounds.  Neither of them are under or over weight.  As long as her ribs are not visible and her back bone does not feel boney when you pet her, she is probably fine at that weight.

Hi there.  You have such a pretty girl!  I would say if kitty has always been this weight, then nothing to worry about, but if you've suddenly noticed she looks thin which led to weighing her, then of course, time for a vet visit.  From your picture and description, she sounds okay, but that's only if this is normal for her.

She sounds good to me. Just like humans, cats are all different sizes. If you are really worried you could try a different type of cat food.
