David, owning relatively uncommon/difficult snakes at 15 is not a mark of valor. Snakes are, for the most part, relatively "easy" pets when compared with what a dog can do physically, mentally, and financially. There's also a large difference in the responsibility between an animal fed once a week... and one fed and cleaned twice a day, walked, and groomed. This is NOT belittling the care you put into your animals, but it's a different order of magnitude, and I would have to say that I'd trust more a 15 year old who was actively dealing with/had actively dealt with a very ill dog or cat and the subsequent treatments.
As a 15 years old I had an epileptic dog that required rectal valium to stop her monthly cluster seizures long enough to take her to the e-clinic so she could be put on an IV valium drip. I believe that was also the year she ate her entire bottle of phenobarbitol tablets and nearly killed herself. I was also dealing with a succession of wild baby birds that required feedings every 20 minutes from 7am to 11 pm. I also had a different dog that was highly dog aggressive because of my own insecurities around strange dogs. And I had a bearded dragon.
I'd already had and bred hamsters (one femur fracture, one abdominal tumor, one three-legged baby keeper with heart and eye problems), parakeets, owned several blue bellies, one of which had epilepsy, I believe, fish, cats, and frogs.
Shelby was the one that really taught me about responsible pet keeping. There's nothing like 75lbs of seizing dog to deal with at midnight once a month or so to open your eyes to the joy of pets. Aussie taught me a lot too because I in a way "ruined" him by being so fearful. He was perfectly people friendly though, adored children, and I miss him dearly.
And yes, I have several plans depending upon what happens. I already know what I'll do with my animals should things end up pear shaped... and I sadly already know what to do if steroids ever cease to work on my dog's sudden bouts of autoimmune-thingy.
