I haven't been able to palpate very well since she tightens up whenever I try and has been especially agitated and twitchy lately. I haven't seen a tail suck but I am seeing what looks like a glow (I don't have any good pictures of her from before I noticed it, but she used to be really dark). So this looks like regular pre-ovulation behavior? Will that huge build she has move down, or could this mean she also has some slugs?
