I've never heard of the implant, how much does that set you back, it cost me £60 per Jill to get them speyed. My mate didn't do anything with his jills, don't know if this was right, whether he was just lucky? Since my daughter owns ours and they're not going to be bred from in the future I just played safe and had them done. Non ferreters don't understand paying £60 to Spey a £10 ferret but that's what you do for your pets if that's what they need. Out of interest what the going rate to borrow someones snipped hob?
