Baby kitten meowing in backyard all day?

you shouldnt annoyed the kitten because there are wild animals at nights time can killed it. it better bring it inside and if you have empty bottle or a clean rubber glove you can poke a hole in the glove and then pour little milk then feed the kitten make sure you hold it gentle in your hands or with a shower towel until tomorrow you can call then bring the cat with you to closer animal shelter and have to sign a paper then give to the the person who work there they will take care of it . or you can call and take it to vet clinic place instead they do take care of unwanted animals such new borns . so that means the mother got killed several days then if the kitten has been there too long. make sure you double check there aint any more kittens out there in your backyard. not too late to go to the closer gas station or market store to buy a kitten wet food can that you feed it .

If she is still outsides then please bring her in. You should either go to your local pet store or look up a recipe for kitten formula and get some special bottles to nurse her with. Make sure you get some nice warm baby blankets and a heating pad to keep her warm. Call your local vet and find out if there is a nursing mama cat or dog that will wean her some vets may know of a mama dog or cat that has lost a litter and needs a baby to love and nurse. Depending on her age she will need round the clock feedings every 2 hours. She will also need a litter box and you will need to teach her how to use the box. You will probably need to her but with a warm wet wash cloth to stimulate her to use the litter box. You will probably need to show her how to dig to China. Just remember the most important thing she needs is love and plenty of milk. Don't forget to take her to a vet as soon as possible.

Take the kitten inside to keep it warm, and get some special formula to feed it. Also be sure to take it to the vet to get it checked over. I love kittens they're so cute. You'll be lucky to have a kitten.

Take it inside, keep it warm. Then take it to the vet for a check up and spaying. You have just adopted a new cat. 

If it's been a couple of days, the mother has probably abandoned it. That means take the kitten and try to care for it or take it to a vet for help. Maybe contact a local rescue to see what can be done for it. Good luck.

Pick the child up, bring it indoors and feed it, make a nice warm bed for it and then decide on a name.  Go to walmart and get a can of Tiny Tiger kitten formula and a little bottle.  Feed the baby every 2 hours.

It sounds like the kitten has been abandoned and is probably starving.  Call your local vet as soon as they're open and ask them what to do.  They may ask you to bring it there or they may have someone come pick it up.

Leave it for it's mother to care for it.

If you take it into care you will need special formula and feeding equipment, some way of keeping it warm, and the stamina to feed it and provide care ever 3 hours for the next week, slowly going longer between feeds until you end up with a fully weened kitten eating 3 meals a day from a bowl in about 10 weeks.
