It could be that your chameleon is just cleaning its eye,
but then again it could be the beginnings of an eye problem.
If this chameleon is in the same cage as the Jackson's that you
had, did you disinfect the cage before you put the baby veiled
in? Did you disinfect/replace the branches in the cage before you
used it for the baby veiled? If not, whatever the Jackson's had
could have been passed on to the veiled.
I always thoroughly disinfect a cage before I put a new/different
reptile in a cage that was used for another before I use it again.
I always use fresh branches...and anything else that I put in the
cage is either new or disinfected. I do this even when both the
previous chameleon was one I hatched/owned for a long time and
I'm replacing it with another one I hatched when the previous
one dies. Its even more important when dealing with WC's.
Its also important to quarantine a new chameleon....keep it in a
separate area of your house for at least 6 weeks before you bring
it into the room with ones that you've already had for some time.
Its important to wash your hands well when you have one in
quarantine...but I would recommend washing your hands even when
you go from one cage/chameleon to another. Its better to be safe
than sorry. I think you only have the one, so it doesn't apply
to you...I'm just telling you in case you get another one while
you still have this one.
What is your set-up? Do you have a UV light (that is not sitting
over glass)? Do you use dust your insects before feeding them to
the chameleon? Do you gutload the insects? Do you have a dripper?
I have kept veiled chameleons for years...and I'm still learning...
but they now live a long time with me....females often
over 6 years and I have a male right now that is over 8.
I certainly hope you have good luck with this little one!
If you haven't had much experience with chameleons, I suggest that
you read all you can. There's lots to know if you want to keep
them successfully.
Hope this helps!
