Hi I have a six month old kitten and want to ask someone with a bit more experience as he's my first pet. He has suddenly stopped using his litter tray, for the last 4 days he is only using it to pee in. I've assumed that as he is eating and otherwise well he has found somewhere else to use (he has open access to a garden throughout the day) but should I be concerned? Also is there a way to train him not to wake up at 4.15 every morning and demand food? He used to wake at 7 ish but for the past few weeks he has developed this new habit! Thanks
