Vets! Do you recommend eCASH for tears?

Hi all! Newish breeder who's still figuring things out. I've had two litters go 9 days past due, and I'm fairly certain that my stud boy's sperm count is lower than usual. After a ton of work, we finally confirmed a pregnant doe! <br><br>It's been a long road, but I got some great recommendations from the community about breedings. I basically worked with my vet to get some advice, and she mentioned eCASH for tears and uterine fluids. Does anyone else use eCASH? I've got a few questions: <br><br>Do you recommend using this product? <br>What volume do you recommend using? <br>Does it work with timed breedings? Do I need to run paramores? <br>Was eCASH referenced in the original breeding guide? (It's not in the pinned post, but I remember someone discussing it in the comments)<br>I would love to hear about anyone's experience with this product! I'm also very open to suggestions if what I'm doing isn't right. I've had a ton of fun breeding, but I'm still a novice breeder.
