Low Air in Cave | 水中洞窟の空気不足 (Pixiv Fanbox)

Ashley the Cat exploring a cave deep underwater forgetting to check his air. Will he be able to get back to the surface in time or suffocate slowly underwater? Author's note: The commissioner for this art has not been completed payment for this request for several months now. Rather than letting it not see the light of day, I decided to post it here for actual supporters to enjoy it. But I understand furry art like this might not be everyone's interests so please let me know if you are not interested in subject matter like this and I will refrain from drawing furry art in the future.
