Question
Is it safe to give my rats branches cut off disposed Christmas trees?
There's a huge pile outside my apartment.
Answer
No,
Pine and Cedar are generally considered toxic to Rats (and many small mammals) pine should not be used as bedding by extension they should not be offered as chew toys.
There are several home remedies (most don't work) for keeping needles on trees, and you have no idea what methods may have been used on the trees that have been disposed of.
In fact many woods can be harmful for a rat to chew on, so making healthy choices on behalf of your rat is important. (still looking for a really good reliable reference, on best rat wood chews)
