I cannot give you an exact size without measuring and it's in storage outside atm and it's nearly midnight but he is substantially larger than a typical plush he would probably come up to my knee at least, and no, they are not sadly as my Mom does smoke and I do on occasion but they also haven't been in the house for a very long time, they have been kept in bins in storage outside in a seperate area.
If you want Neko I can take a picture of him propped up next to me tomorrow or the next day {very busy day tomorrow} so you can see exactly how tall he is, and I can spray him down with some Febreeze and such.
