Spinach is toxic when more than small amounts, make sure u research what u feed before u actually do it, u dont want a poisoned reptile im sure my cham will eat rocket, but he doesnt tend to often so i dont usually bother, he prefers moving prey. Some say avoid brocolli as thats apparently the same, though ive read a few using it. If I ever see someone say something is toxic though, i wont use it even if others say they do, just to be on the safe side.
Just a note to add to this, I'm a strong believer of what is bad/good for someone else may not neccessarily be the same for u.
Chocolate is poisonous to dogs, everyone pretty much knows that, and most dogs after large amounts of chocolate, particularly chocolate high in cocoa like cooking chocolate, will drop dead within 24 hrs after serious side affects of laboured breathing and the runs.
My boyfriends dog tends to steal chocolate on many occasions. Last easter she stole a box of chocolate ducks from marks and spencers and ate them, she's also been caught indulging on boxes of chocolates at xmas when nobody has been looking and she hasnt dropped dead yet and she's an oldish dog, probably only a few years left in her if that, but still she hasnt dropped down dead from chocolate yet other peoples healthy dogs have been seen that their health declined rapidly after eating chocolate.
Point is, nothing neccessarily is affect the same way by the same factors but if their is an area of doubt, avoid it just in case.
make sure u read WHY something can be poisonous aswell. Potatoes can be fatal to humans when kept in light, because when they begin to photosynthesize the toxin levels actually rise and do actually become fatal (scary really) mango skin is also toxic and part of the stem. I wouldnt really feed brocolli because of the digestion issues u may have, runny cham poo would get me quite worried!
here you go, if your after cultivations growing in your enclosures, this is the guide to follow.
note: these plants are on this list because they are also edible. chams like ficus trees in particular
also note there is a risk stated about the sap of ficus trees on this list. Champ, my cham, had a ficus tree in his enclosure with is old keeper with no problems. As the rubbing is most likely to occur when shedding, remove the tree from enclosure during those periods. Must also stress that you cover the soil at the bottom with large pebbles, chams tend to be silly and eat soil which is not good for their tummys.
You see i thought broccoli would be fine as i got it off a list of plants suitable for chams, it was posted on these forums, so thats the main reason why i went and brought some, do u think it would be best to take it out and just leave the watercress in?
well like i said, its fiborous, meaning it tends to result in diarrhea, which obviously isnt too pleasant. As long as it doesnt take too much of a fondness for it and gutloading himself with i wouldnt bother taking it out, just watch he doesnt go crazy for it. Dont forget to cover your soil up as well. Use large pebbles or pieces of slate that are too big to be swallowed.
