[Gpdd] [CARE] sticks for snacks?

[XraphieX at aol.com]

My mom has an orange tree in her backyard and since trimming it, she's been 
giving my 2 piggies branches to gnaw on. They seem to LOVE them... I figure 
it's a nice treat for them, since it keeps their teeth in "good working order" 
and probably tastes a bit fruity... Does anyone know any reason that she 
shouldn't let them have as many sticks as their little piggie hearts desire?
