Well, the only way you'll know if it's too niche is by asking and seeing what the responses are. If posting on lemmy doesn't get you enough information, you might try posting on reddit, they bring the information back here tob possibly help others in similar situations. I mean, I've left reddit, but if my cat's health was potentially at risk, I'd ask anyplace I could get a decent answer.
Community search for vet advice
Is there a community for asking questions about pet symptoms? Maybe a place where vets share advice?...
