Willks has explained, by nature cornsnakes have a wide natural range, but most come from a range where the climate is similar to the UK, so instinctively they would normally be exposed to cool temperatures at night. By turning the heating off at night you are mimicking that natural occurrence. Most houses in the UK will drop down to 18-22c at night in the middle of winter. His viv will retain a little heat, so it could be a degree or two higher. You need not worryThat’s great Malc thank you, I can open them links on my phone so that’s a great help.
I just have a couple more questions and then I will leave you in peace from my pestering.
I’m not quite understanding the dimmer stat. I get how it works etc, but you suggested putting it on a timer to go off between certain hours at night, how will his tank stay warm during the night if it’s not on? Sorry if that’s an obvious question.
I can't answer that. Unless there are visual signs such as constant gaping, convulsions or it's bleeding from the vent then there is no way of telling if there is anything wrong internally, if he is on his way out or if he is experiencing pain. But this could be a simple phase that he's going through and is otherwise in good health other than being a tad overweight, and may go on to live for another few years. If you want to get him checked out then by all means contact a vet, but in the current confused lockdown situation and as it's not an emergency, the vet may not be able to see him. And may give you similar assumptions to those already advised by forum members.Lastly, if he is coming to the end of his life, are there any signs to look for?
At what point do I take him to the vet if I think he’s suffering?
We can make all the suggestions we want, give you possible improvements to his habitat, and advise you what we may do if we were in similar situations, but what you do with that advice will be down to you, your finances and personal circumstances.
