Wasn't it wild boars? They can be huge and make crazy sounds.
I love foxes... check out this video my bud made, with a Sony Handycam put in front of a badger den during one night... image quality is poor but content is cool :-)
Mice, fox and badgers
Edit: and bm it's a pity that the rabbits are gone now because they're so cute but it's nature. I had a rabbit living on my yard for 6 years, she was part of the cat family, very cute, then one morning I found her half eaten, put a cam there and the next night a cat turned op looking for the remains of the rabbit. Wasn't my own cat, but probably from a nearby village. Now imagine that, I live next to a forest which had loads of foxes living in it, but he rabbit didn't get killed by a fox but by a stupid cat.
