Refill with the soil that is there first and foremost. If the soil was too scattered to refill the entire hole, then use garden soil or sand. It should mound up slightly to allow the soil to settle in the next few years. If you have bermuda or Kentucky bluegrass, the grass will cover over by itself. If you have fescue (like the Marathon varieties), then you will need to reseed. I would reseed now and not wait until it gets warm. In your area it might be wet and warm enough for the seed to sprout by itself in January.

Deer leave ragged ends on branches they browse. Good video showing this close up http://tinyurl.com/qc4hqqf (go to full screen for detail). Bunnies can only reach as high as they can stand on their hind legs, and are apt to leave a mess of torn leaves, stems & flowers strewn about. But they can jump to higher areas (porches, chairs) & nibble plants from above. Never noticed squirrels munching plants, but they get plenty of tidbits from bird feeder scatter. Our house sits in a clearing surrounded by woodlands, so somebody seems awake at any hour of the day or night scouting for supper. Aromatic plants like lavender & beebalm guard the borders near roses & floppy plants that obscure sure footing cover any bare ground around perennials, many of which are deer resistant, but nothing is deer proof. Have to fence the garden phlox when it buds, since deer have climbed the steps & gobbled down the blooms from the porch. Apparently, that's irresistible. They haven't bothered the hydrangeas, apart from sampling a leaf or two over the years, but in my son's garden miles away they browse his to stubs & bypass the Peace rose surrounded by lavender. Sedum Autumn Joy is a big draw for the fleshy leaves, so I leave the old stems poking out till getting around to caging them before the foliage outgrows their deterrence. Typically it's a curious young buck that comes exploring the flowers on his lonesome around here. Several small deer families graze on the back lawn & rest on the edge of the woods, but they seldom bother the plantings unless it's a hard season. Haven't noticed any damage from other woodland neighbors, though the turtles will clean up fresh fallen rose petals & help themselves to a few viola blooms. In the years I find heliotrope to grow in the porch boxes, a hedgehog couple can often be glimpsed sitting quietly next to them, apparently enjoying the fragrance as much as we do, without disturbing a petal.

Squirrels like the sugar in the shoots, and once they discover your free salad bar, you need strong measures. I've tried a number of things over the years and the only thing that works consistently is a physical barrier. Go to Home Depot or equivalent and buy a roll of wire mesh with about a 1/2" square opening (it's near the chicken wire); they even make this product with a green vinyl coating. Cut pieces big enough to curl into cylinders about a foot high and fit them around any new shoots coming up; if the shoots are close together you can make a bigger cylinder and fit it around several of them, but don't make it so big a squirrel can jump inside. You can attach the top end to another culm with a twist of wire to stabilize it. Let the shoot grow up inside the cylinder. When the shoot is 1'-2' high it will have hardened off and you can remove the cylinder without fear of losing the shoot anymore.

Two points. Torture is a relative term. Is it torture when a lion catches an antelope and begins eating it before the antelope is completely dead? Is it torture for the antelope to be chased by the lion? Is there really any difference between the terrified antelope and a cow being forced up a killing chute and killed quickly with a blow to the head? Humanoids have eaten plants and animals since before we were Homo sapiens. We killed animals however we could. Forcing herds over a cliff and leaving most of the animals to rot, since there were too many to eat before the rest began to decay. Most people in the US are appalled by the thought of eating dog or horse meat. Because we have enough wealth to keep those animals as pets, making them more special to us. I can't visualize eating monkey meat and I would never open a clam/oyster and eat the insides. I have tried roasted opossum(once was enough---greasy, nasty tasting) and like rattlesnake. I've butchered chickens, hogs, and cows, processed them, cooked them, and enjoyed eating them. What people eat is what they grow up eating. Point two. Everything dies. Some things die quickly, some die slowly. Ever see a cow or deer with wasting disease? Or a starved horse or a dog? Pitiful sights. Makes me mad. People have the ability to choose what they want to eat. Those same people have no right to force me to abide by their beliefs---like PETA(I like my version of P(eople)E(ating)T(asty)A(nimals). You want to eat chocolate covered spiders? Have at. Don't be surprised if I say "No Thanks".
