How old is this kitten?

Around 3-5 years old.

Looks like what everyone else is saying: 8 or 9 weeks.

She’s adorable!!

older than 8 weeks 10-12 is my guess

8 weeks. Maybe 9 weeks. Or 10 weeks. She is too small to be 3 to 4 months

About 8 to 9 weeks old, the vet will be more accurate by checking her teeth as they can tell that way by which teeth have come through for her,she is one lucky kitten that you went out of your way to help her....

IMO looks to be about 8 weeks old. If you plan on keeping the kitten, you need to have it wormed and started on shots. Since its a female (tortie and white in color) plan on spaying her by 4 months old so she doesn't breed.

Probably 8 weeks or so anyway. If she is eating regular food without difficulty, this would be about right. But she may not have been dumped. My daughter once rescued a kitten that was living with a number of other cats/kittens under a dumpster at a Church's chicken. Employees told her there were often litters of kittens around there. Most of them are skinny, but you will be amazed how much a little decent food and love with do for them.

I don't know how old they are, but they are very cute and fluffy -.-

I'm not much help, aren't I?

i think your vet rnight know when you go there tornorrow

Very hard to tell. The vet can tell you.
