I noticed today that my red tail has a very large bulge towards the end of her body. I soaked her hoping it would make her poop but she did not. I massaged it a little bit and it is very hard and chunky. She doesn't look as stretched out anymore but I took some pictures. Should I keep soaking her everyday or is there anything I can do? Vet call? I use aspen and I'm not sure of the last time she had a BM. Possibly 2-3 weeks ago.
