Is pet cryopreservation good for the image of cryonics?

If Katja is correct that cryonics is far and far is actually meaningful then almost certainly not.

Will people upload pets? Assuming life as an emulation feels different from life as a biological organism is it ethical to upload animals? The transition might be strange and uncomfortable but we expect at least some humans to take the risk and live with any differences. But animals don't understand this and might not have the mental flexibility to adjust.

If one is worried about this one could presumably keep them in a simulated environment very close to the real world. But animals may have a lot of flexibility in this regards. Look for example at dogs who learn to walk after their back legs have been amputated and replaced with wheels. Or dogs who learn to walk on three legs after one is amputated. Or at cats that manage to hunt when nearly blind.
