I don't actually know these neighbours and have never spoken to them, but my husband doesn't get along with the man because of a fender bender in the past, so I don't feel comfortable going over there and asking. They live at the end of the cul de sac and their cat used to visit me all the time. I never fed it, but I do have a cat of my own who I leave food out for, so the neighbour's cat would sometimes have a nibble of that and play with my cat.
He was/is such an adorable cat. I think a Russian Blue or Korat. A bit aloof and skittish around strangers, but friendly and "chatty" with people he knows. This cat has been visiting my garden for three years almost and would always randomly appear most days. In the past, the most he ever stayed away for was three or four days, but now he's been absent for almost three months. I didn't take much notice at first because I thought maybe he was just staying away for some reason, but after two weeks I started worrying and checking local facebook pages to see if any dead cats had been found/reported missing--nothing. I checked the neighbour's facebook page, nothing posted about their cat being missing.
I know it's silly to get so attached to somebody else's pet, but I don't like not knowing what happened to him. For all I know, he could be at his own home relaxing and just got sick of my house for some reason, but I'd hate if anything happened to him like a dog attack or hit by car. I think about him a lot and just hope he's okay. But no, going over there and asking isn't an option.
Have you ever gotten attached to a neighbour's cat?
