All my cats ever want to do is sit by the pool, watch tv, or gossip on the patio.... (PS No, I don't dress up my cats, I found the sunbathing picture on the net but I thought it was the cutest thing)

I went ahead and shoved in more shavings, maybe raising the level by a couple of inches. Still nonstop pecking. So I added another couple of inches. Pecking stopped! Flicker then sat in the hole looking out for much of the day. Now about ten days later she may be sitting on eggs. Fingers crossed. So the advice to fill the nest box fully up (with sawdust), as compared to the advice to only put in 4 inches (of wood shavings) seemed to work better in my situation.

I have found the best way is to just act normally and let everyone do their thing. Monitor the cats and have a squirt bottle with water ready in order to disuade any bad behavior on anyones part. Cats seem to need to be able to spend time learning who is boss. Having one cat put another in its place is normal behavior...just make certain that a fight does not break out by being alert...good luck and kudos to your for fostering.

Thank you everyone for taking the time to give me your advise. Last night I continued with pedialyte and he ate some more. This morning his appetite seems to be getting better. He's still somewhat lethargic and still limping noticeably but less than yesterday. He's eating canned food, but noticed his gums are somewhat pale, is that normal? He's still getting pain medicine and his wound isn't swollen . It seems like he's getting better but just worried about his gums.
