i still catch glimpses out of the corner of my eye, of my old cat Peanut. my kids do too. the funny thing is that she's the only one who stayed after going. she was a moody anti social cat who never forgave humans for the bad start she had. she only tolerated us but towards the end she showed some affection and in her last few days she let me have some lovely cuddles, that only ever happened before if she was dopey after having teeth out. all her gratitude was evident in those last few hugs and strokes. maybe thats why she stayed. i've never seen or sensed any of the others that have gone on although every now and then i smell my old dog, even though the carpets and furniture have been replaced since she went. it's less and less now but i'm ready to let go of my sadness at her passing and remember her with a big smile so maybe she thinks the time is right. i think it's lovely if they manage to come back for a bit, it eases things for those of us left behind
