I have two kittens that are probably around 8-9 days old that look a little sick and dehydrated. Would you take these kittens in such conditions?

What you should do is go to the Modesto Animal Shelter on Crows Landing Road and tell them that the kittens are from Modesto Area and they will take him from you make sure you don't go to Turlock animal shelter because they are a kill shelter and they will not rescue the kittens they will probably kill them but the Modesto Animal Shelter on Crows Landing Road which is called Stanislaus County Animal Shelter they will take him from you and take care of them

I think they would just go over and tell them, you found them if not they will charge you for the cats.

Yes if you just drop them off as found I believe they will help

If they're yours it costs you. If found you can drop them off
