just seen a little blighter on our bookshelves at lunchtime!!!! we had mouse poo last yr under the sink and my cat caught three (traps didn't work at all) but no signs since then tho i kinda figured they're around, just not coming 'upstairs' into human space which i can live with. SLIGHTLY freaked out now tho as we have a 5 mth old & if they can climb shelves can they get into cot/onto sofa??? & wot about her playmat and toys that have been on floor?????? advice?
