Sorry to hear he's not eating again...got anything different to offer? Have you tried crushing a piece of dried chicken or salmon over his food? Sometimes Luci gets picky and won't eat another bite of FF pate...I have Sheba pate, FF pouches and FF appetizers on hand for a little switcheroo...sometimes sprinkling a crushed piece of dried food over the FF pate will get her going...Most of the time she's a good eater - but sometimes she just seems to get tired of the FF pate's...forte flora is also a good sprinkle over - but I haven't tried that one yet.
Best to you and Sebastian today - hope you can find something to peak his interest in eating...
