Hey guys. I know I haven't posted in a long while. But I have a serious question. A couple of minutes ago, I started hearing a very strange sound. I thought that it was one of my cats trying to hack up a hairball. It turned out to be Jasmine, my almost 6 ft. Colombian boa. She had her mouth stretched wide open, and would make a hissing noise, then a gagging noise. She did it at least 5 times and then stopped. Her body was very rigid and one part was flattened. She then moved a bit and made a few small hissing sounds. Was she trying to regurge??? She was fed on Monday so it has almost been a week. Is there something more serious that could be wrong with her? Please, any help that you guys can give would be much appreciated. I need something asap so I can take her to the vet if needed. Thanks, Tessa OH! She was also very aggressive after we fed her last. She struck at my boyfriend as he was trying to get her out of the tub. She has never been the least bit aggressive, which leads me to think that something may be wrong.
