Toilet bowl water "disappearing"

The water in my toilet bowl seems to be gone after a day or so. It is a largely unused toilet, in a 7 year old house. I'm thinking that the wax ring is old and cracked, but wouldn't water be leaking into the house? ANd there is never any water around the toilet on the floor. Any other possibilities? Thanks in advance for any advice

Water is held in a toilet bowl by a built-in trap in the toilet itself.
It won't leak out of an unused toilet unless there is a crack or other defect in the ceramic body of the toilet.
Sounds like you may a partially clogged vent up on the roof.
If a vent is clogged or partially clogged, any water draining through the drain/waste/vent system will siphon water out of the nearest fixture to create another "vent", which would explain water being siphoned out of the toilet bowl.
Check the vent pipes on the roof for birdnests, thick spider webs, leaves, debris, etc. or anything else that may be clogging it.
Clean out what you can reach by hand, and then flush it with a water hose sprayer.
Good Luck!

Thanks Mike,

Sounds like good advice, it's my dads house and the vent is on a very steep pitch and very high off the ground - looks like an early dads day present!!
