Unofficial color list for The “Sitting Cat” collectible figurine, manufactured by Mosser Glass. It can be challenging to identify colors on the Mosser sitting cats for a number of reasons – beginning with the lack of documentation from Mosser. The list is organized by color family, with descriptions and links to images where available. For consistency, nearly all of these photos were taken in the same location under similar lighting conditions . (Where did I get this information?)
Colors which were rerun in 2023 are flagged with an asterisk (*). These are all marked with an “M” in the state of Ohio on the lower back towards the right. The originals should have a plain “M” on the lower back towards the left.

2023 Colors – Sitting Cats Redux:
2023 saw a massive increase in demand for the vintage Mosser sitting cats, with sales for vintage pieces running well over $100 each! To meet demand at an affordable price, several independent vendors commissioned Mosser to make special orders of the cats exclusively for them to sell. ALL OF THESE CATS CAN BE DISTINGUISHED FROM THE ORIGINALS BY THE “M” IN THE STATE OF OHIO ON THE BACK TOWARDS THE RIGHT.
In order of their release, these colors were:

Midnight Blue – A mixture of crystal and black that turned out a beautiful dark blue. Used to produce fluffy kittens and sitting cats. Sitting cats were made in solid color and opalescent.
Where did this information come from?
Unfortunately, Mosser did not keep very good records during most of the years that the sitting cat was in production. There is just a small notebook – partly typed, partly handwritten. Two pages list sitting cat colors, another lists colors for the cat plates. Some of them have months / years listed, most do not. There are no color descriptions on the list and some known colors are not mentioned at all.
The list on this page was aggregated from:
- The Mosser Glass notebook pages.
- Several Mosser catalogs from 1979 through the 2000’s
- Conversations with other collectors
- Mosser dealers. A good percentage of my own collection was from a former Mosser dealer and most of those items came to me labelled. Also, product lists on old dealer sites, from archive.org (not 100% reliable).
- Other products Mosser was making at the time where the color names are known. Jenny / Josh, clowns and collies – with the caveat that some colors were sold under different names across products. Jenny / Josh and the clowns were sold in labeled boxes and often kept with the box, making their colors easy to identify.
- Standard industry names for types of glass produced at the time, for example, persimmon is likely to look like persimmon glass.
- Glass produced by other glassmakers (such as Boyd). Boyd produced items in a ritz blue and a cambridge blue in the 80’s.
- Standard color names – Pantone, etc.
