Hi All

I wonder if anyone has experience this. A few days ago, I and wife was
watching TV, and we heard something scratching our patio door. It was about
10 PM at night, and we went to the patio door to have a look, but could not
see anything. But scratching noise was still keep coming into the house
rather loudly. We were not sure whether it was outside of the house or
inside the house. I went out through the patio door, put the security lights
on, and looked around, but could not see anything at all.

Next day samething happened exactly same time 10 PM at night, scratch noise
from the patio door. Went there, and looked around but nothing. This time I
found out the scratching noise was coming from the floor of the kitchen. It
sounded like scratching with some sort of paw or claw. I hit the floor with
a shoes a few times making loud noise, but the scratching noise did not
stop - it went on a few time, and got quietened.

What could this be? Our house is newly built about 2 years ago, and kitchen
floor is stone tiled. We also used to suffer from a lot of ants coming into
the kitchen, and crawling around the stone tile floor.

cheers
