I'm trying to thin my BP/Boa collection out.

I sold 3 ball pythons last Saturday; 2 breeder size female ball pythons, and 1 breeder size Pastel male. The females were around 5 years old, I had purchased and raised them since they were hatchlings. Both about 2,000 grams, currently off feed, and overall healthy. No wheeze, not thin, no mites, no drooling, no scale rot, etc. The male, about 1800 grams is in equal condition. All animals had been kept in racks, in my reptile room. I sold the females for $40 apiece and the male for $30.

The buyer contacted me this morning telling me that the 2 females have passed. And seemed to be questioning their health. Snakes were inspected before sale. I have seen no video or pictures of these animals. I have not vetted my collection and have never had health problems since beginning my collection about 7+ years ago, with the exception of one animal that I purchased a year ago with minor scale rot, which I cleaned, and put ointment on, and he is now fine.

Animals were sold via a local state FB group, buyer picked up these animals in person. The buyer lives 2 hours away. The buyer has mentioned that he has a "vet friend".

As a seller and reptile hobbyist that's on the fence with becoming a hobbyist breeder, I don't want this to become one of those Facebook/Fauna "drag my name through the mud", type of situations. I have sold other animals in my collection and have never had a problem and still keep in touch with one of my buyers.

Healthy animals that were "fine Wednesday", now deceased on Friday (the rest of my collection in my home are fine) seems odd. I feel that husbandry, maybe a heat spike, would kill these animals. Or exposure to chemicals. I have a friend that is also a reptile keeper and feels the same. The buyer mentioned that he works on cars. He also 5 other ball pythons. I'm not sure if he quarantined my group from his. He has children in his home. I don't know if these animals expired today or yesterday, I don't know if he has refrigerated the bodies.

I have priced a necropsy, one near myself and one near the buyer at $100-$250 plus. I don't feel like I would trust the "vet friend". The buyer has not asked for a necropsy or refund, nor have I offered.

The gist of this post is that I want to do the right thing, without being scammed, ripped off, etc.

Here are out exchanges.

Buyer: Morning. I have some sad news.

Me:What happened???

Buyer: I found the two females dead last night. I'm not sure if they were sick or stressed out. I'm not sure what happened. I went to check on them & dead. They were doing fine Wednesday.

Me: Damn...that's unfortunate. I'm sorry! The girls were fine here and my other animals are okay. I can't imagine stress. I've moved with them a couple years ago. They've gone from tanks to racks to bigger then bigger tubs and have been okay. They weren't old, 5-6 years, and unrelated.

How were they being heated? Could there have been a heat Flux? Thermostats? What were their Temps? How were they housed?

Me:UTH set at 88-90 during the day at night I have it dropped to 80-85 on a thermostat 40g. All my other snakes are fine. The male is fine also. Going to try to feed him tomorrow since it would be a week since I got him and he has been left alone and he's in a 40 gallon tank also

Hmm... I don't know. What kind of t-stats? Are they new? I've had a heat mat fail on me before. Have you tested the heat mat/tape since? I'm not trying to pick at your husbandry, if I sound that way. Just trying to wrap my head around it and figure out what could have happened. I just checked on my collection and everyone here is good.

You mentioned that you purchased new tanks. Were they cleaned before use? And how? Maybe a reaction to a cleaning product? I clean with either original Dawn or F10. If so, maybe the Pastel should be moved back to a tub just in case. Sorry, just trying to brainstorm. Keep me updated.

Him: I'll have to check the brand when I get home I don't remember what it is. Yes they are about 6months old. I spent like $250-300 on it. It Controls 4 pads at once. I turned it on before I left to get them to insure the tanks were warm when I got back. I hooked up a alarm system on it if the pads didn't get hot.

Yes I cleaned them with dawn mid soap & hot water like I always have done. That's the best way I has told. I did it about a week before I got them. Nothing else has been in there. Funny thing is I put the pastel in a tub & he got out one nite

Me: Hmm, sounds like a Herpstat or one of the other premium t-stats. Probes were placed okay? Thermometer with the Tstats? & you said you use aspen bedding? Yeah, that's how I would have cleaned the tanks.

Have you rechecked the setups? Heat spike? Anything else, I'd think, wouldn't take them both overnight. They were okay when they left, no wheeze or other RI symptoms. They've been off feed, the lighter one longer than the darker one, had good weights. This is upsetting. I've had them since they were tiny and have never had problems with either.

I've never had a jailbreak with the Pastel, that's surprising, only the lighter normal.

What do you think?

Him: It might be a herpstat. Yes. The probes are on the heat pad itself. Yes aspen. Yes rechecked everything to make sure nothing on my end went wrong. I even used a laser temp gun and it said 89. Yeah it is upsetting. Idk what went wrong. The first two nights the pastel was acting crazy so that when I put him in a tank. Then he relaxed so I put the other two in tanks also. They were all hooked up to the same tstats so I would think if there was a heat spike he would be dead to or something. I wish I checked on them Thursday but I didn't. So I'm not sure when they passed

What are your suggestions with how I proceed?
