Dangers to sugar gliders

[Angi]

I was thinking that it would be really useful to prospective keepers like me and new keepers to have a list of dangers to sugar gliders, as I have come across a few whilst reading. This list could be updated as new dangers come to light in order to keep everyone informed. maybe we could have a sticky topic?
In my reading so far Ive discovered the following can be dangerous (can the experienced keepers confirm these as I know you shouldnt believe everything you read - but I would rather be safe than sorry).

Onions - extremely bad for suggies?
Catnip - can be fatal?
Grapes ( possability - I would rather avoid them after reading about problems with severaol other mammals)
Wire wheels - solid ones help prevent accidents.

Yep - all you should avoid all of the above.

Also Rhubarb
Tomato PLANT
Apricot, peach nectarine wood (basically everything except the fruits flesh)
Fruit seeds in general 

and once my addled brain starts working again there will probably be more I can think of!!

[Angi]

I thought I would add a few others  and maybe break them down into dietary, household, enclosure  groups etc.

Standing water - baths, toilets etc
Uncovered plug sockets


Plants - some are poisonous to suggies - does anyone have an up to date list?

caffiene

Im quite sure there are lots to add, but I will leave it up to the experienced keepers as im only reading and reseraching up to now

I can add most certainly water is BAD

Also - Cat Flaps.

Also - Leaving Sweets laying around, trust me when i say they soon figure out how to unwrap everton mints!

Lightbulbs - they get dead hot there are plenty of lamp shades which totally enclose the bulb preventing the suggie accidently burning themselves
