Yes, Dr Jones is back - it's a series, so he'll keep coming back for a few weeks yet! ;)
I hope you saw the first episode last week - I did and thoroughly enjoyed it - not at all what I was expecting.
I had no idea for instance that baby adders pack as much venom in their bite as the adult snakes which is very handy to know.
I saw a baby adder in the summer - slithering across a busy beach car park and almost picked it up to carry it to safety. Luckily I just watched it instead and allowed it to find its own way across.
Anyway, onto this week's episode:
Teenage Mutant Ninja Turtles may have been all the rage in the 1990s but they sparked a craze for the real thing - leading to hundreds of terrapins being bought and subsequently dumped when their owners grew tired of them.
Rhys and PC Mark Goulding with a boa constrictor:
Terrapins are not the only animals that irresponsible owners are taking on; only to dump or release into the wild when they grow too large or unmanageable.
Rhys also has his hands full with a terrified bosc monitor lizard suspected of being bullied by a larger beast, who has even ripped off some of its digits, making it difficult for the poor lizard to climb and dig.
Rhys, who hails from Cardiff, reckons zoos and wildlife parks are full to the brim with former escapees and he's already taken home several specimens who would otherwise have been put down.
