Cat food dispensers - any good?

[qwertina]

We are going on holiday for the first time since getting a cat. We have a couple of retired neighbours who have both offered to feed him, which is great. However, they both get up late - around 10 am. The cat is starving by about 6 - 6.30, when we get up and give him his breakfast.
Does anyone use the automatic dispensers, do they work? Or will the cat be ok fed much later than usual?

Was thinking of something like this one www.ebay.co.uk/itm/like/200939319633?hlpht=true&ops=true&viphx=1&lpid=95&device=c&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0&ff12=67&ff13=80&ff14=95&ff19=0

My cat eats from that. Get one. He might need few days to get used to digging next drop down as it gets a bit stuck sometimes. Then your neighbours just check it and wiggle it
