I have a indoor kitten he is only 16 weeks old we are on the first floor flat and he keeps on crying

You can also put a clock in the bed. They are missing mommy. Once mine were fed and helped defecating and placed next to each other they slept until they were hungry. That was usually the only time they woke up crying cause they were hungry. I have bottle fed kittens at least four times.

He is the only kitten you got from the litter so depending on how long you've had him he may be suffering from separation anxiety. To help cure this: If he sleeps in a room alone put a heating pad turned on low setting, wrapped in a towel, for the kittens bed. Lay a worn shirt on top loosely for the kitten to snuggle into. The familiar smell of you and the warmth like snuggling with someone will ease his anxiety and quiet things down.

You need to take the place of its mother. That means handling it by stroking and tickling and letting it sleep close to you - cuddle him up to you and let him sleep with you. You also need to play with a kitten to take the place of its siblings - it is a baby and needs comfort and companionship. They hate being alone when young, Like puppies small cats need company. Later as adults they can choose what they need easier but also as adults if nurtured they will remain affectionate and well balanced. Your cat needs you!

your problem is simples your kitten can see the outdoors and wants to xplore cats are wild animals at heart and dont like to be kept indoors they just lern to deal with it as they dont have a choice you will hav to trust your cat with the out doors dnt feed him/her before you let them out as they will cum home when hungary

When we adopted our kitty, she also kept on crying all night. Finally we got her on one side of the bed and pet her so that she could fall asleep. It was like a little baby, just needed lots of attention, love, and care. Eventually she would get on the bed and sleep with us. She still does.

You should get another cat for companionship.

yep, your kitty is a baby after all and needs attention...the more secure she feels the less she will cry, and the only way she will feel secure is if you show her you love her
