Hi, my husband brought home a new snake and it appears completely healthy and friendly, the people he got it from said he/she eats well, and when he brought her home she had a normal healthy bowel movement and everything seems fine EXCEPT I was horrified to see she has a huge lump on her tail around her anus - my hubby said the people had her for about 1-2 years and she has always had this lump and they have never brought her to the vet. I gently felt the lump and it feels fluid-filled. Any idea What could this be? I realize she will have to go to the vet
