My rep vet said my monitor has a bad deformed lung and other problems. Its looks really bad. He said its best to put it asleep. It no longer eats and its always looks in pain. The nurse said I could cold it. I asked what that was. Does putting it in the freezer hurt it? Or should I just let the vet do it. I dont want it to suffer no more. My other monitor is fine and he said it was in good health. I keep the Aquarium very clean, change the big water bowl 2 times a day change the substrate every 2 weeks, Keep heat on the bottom, Have a uvb 5.0 light and heat lamp.

The healthy one is perfect. I feel bad I have to let one go. But I dont want the one to suffer and shrink away. I was told to gentle just put it in a towel and put it in a freezer and it will go asleep and feel no pain. Is this true? Or should I let the vet do it ? Thank you
Putting an animal in the freezer is painful at first, then after a while it will fall asleep and eventually die. Put your hand in a dry bucket of ice for a while, and feel how it starts to burn, That is how it will feel for your monitor.
The vet might mean putting it in a CO2 chamber, much like people do to feeder mice and rats to kill them humanely. It deprives the animal of oxygen causing them to sleep and die.
BTW, very sorry to hear about your monitor, I lost my pride and joy 9ft albino burm to the same disorder this year.

How much does the Vet charge? If it is reasonable, consider letting the Vet exterminate your pet. He probably will charge around $25.

Not really. They've done studies on them that shows that a reptile does not react to hypothermia in the same way that a mamamal does, they do not go to sleep and are fully aware as they freeze to death. Emotion: sad Freezing is considered inhumane for mammals, which DO go to sleep when cold. I think the only animals where freezing is considered ok are fish and insects.

The injection doesn't cost much, if the vet charges at all for it (the last pet I had put down the vet did it for free). They go to sleep warm and comfortable, and that's it.

Yes, it's a very painful way to kill a reptile, better to let the vet put it out of its misery
