The picture below is not very clear (and it's not a thumbnail, it's full size), but it is special.
The little tiger's name is Linus. The year was 1970, and he and Victoria (the not very visible calico) were our cattens.
You can just see Linus wearing a collar, for previously explained reasons.
(The reason for the poor quality is the photo is off a DVD, specifically a chapter heading. The DVD was transferred from analog VHS tape transferred from 8 MM film. I'm going to try to track down the original family 8 MM to get a cleaner video and stills.)
