Have Cat Questions? Ask a Cat Vet Online.
Hello my name is***** but you can call me Dr. H, and I am a licensed veterinarian. I understand that your pet Jake has some large masses near the tail base and has not been feeling well for the past few days and seems constipated.
To answer your question, yes cats can get hemorrhoids, although rare. More commonly they get megacolon (enlarged colon) that leads to constipation and obstipation (inability to defecate).
I would very much like to see a picture of the lump on the skin. You can share a photo easily by uploading it to your computer and using the button just above the chat that I believe is labeled as "Add photo" or "Share file". Let me know if you have issues and I can have a customer rep help you along.
- Dr. H
Also can you specify what symptoms Jake is displaying when you say he isn't feeling well?
