we have two 9 week old kittens and one of them wets in his bed during the night, he otherwise goes in the litter tray all the time, both kittens are boys and brothers they get on well together anybody any ideas please
Before he goes to bed, take him and place him in the litter tray, see if he'll wee before bedtime. Take away his drink dish after about 9pm too - what time do you feed them in the evening? They are still very little - he'll probably get the hang of it soon.
Just developing at different paces. Just like human babies!! Do what boxtops suggests. He obviously uses the litter tray and knows what is is for. His bladder just needs to mature a bit more.
Are you keeping the litter tray scrupulously clean as some cats are fussier than others? I don't mean to be rude but the is 99% the cause of cats not using the litter tray and perhaps at night it gets used and the litter not changed as often as in the day time. Just a thought.
