Nana, don't just feed them. More important, you need to spay them. Use the feeding to get them close enough to trap for spaying. Spaying is more important than feeding. Because they will give birth to so many kittens and multiply that your neighbours will be even more angry and blame you and you will not be able to feed any one of them, not to mention the helpless kittens that they will catch and put in plastic bags/boxes to dump in longkangs and garbage dumps. It will break your heart!
