Danny, an old friend of mine passed away two years ago, been 30 years since he had bobcats for urine collection. Going through his sheds and out buildings I acquired 10 gallons of properly collected and handled bobcat urine. Has been exposed to -20 up to 105 off and on for 30 years.. Today you can pop the lid give it a few minutes to air out and boy does it smell awesome. Nothing I have even comes close. No replacement for quality.
