Hi everyone. First time posting here and desperate for help . About a week ago , my kitten age 7 months had some hair missing at the very end tip of his tail . He didn't seem as if he was hurt , or in pain . Later that night as he climbed up in my lap , I took the opportunity to make sure that the tail was ok and despite some hair loss , his tail looked and felt normal. This is when my nightmare began . Seconds after looking at the tail he bit down extremely hard at the tip where the hair was missing. This biting behavior lasted throughout the night and by the next morning he had bit down to bone . Took him to the vet , she said it was probably a bug bite , and amputated the tip where the bone was showing . The next day he went home , and 3 hours later he had already bit the stitches out . Went back to the vet , and got stitched up again and went home with a e-collar. However ... He is still trying to bite the tail . He acts completely normal until he sees his tail. Then he growls, hisses, and his anal glands leak out . I have researched FHS but his tail biting seems to be his only symptom. I am a stay at home parent , so he always has company with me . He never seems stressed or in pain , he just acts as though hus tail is his worst enemy . Please if you have any advice for me and my sweet Nacho , it would be greatly appreciated. I have researched so much about tail biting, but nothing seems to fit other problems. He is neutered if this helps . No fleas and UTD on shots .
