Wood stalk is very helpful for getting sustainable wood and I usually use bone or leather for furniture and blocks anyways. Not so sure about the jack rats, I've never encountered anything like that.
My seed stockpile is pretty empty, I didn't embarked with any plant since the carnivorous state of my little friends and those fast breeding jack rats.
And now I'm in a middle of a human siege, surrended, protected by just my walls and cage traps, without wood, juice, jack rat meat and jack rat bone/leather. And some of my militia bolds are missing limbs, since the last siege where I couldn't pay for the wood for the sweat lodge.
At least I have fish and two gremlings (which I have from the very beginning of the fort, a male and a female, but they seems to not like each other, no little gremlings for me), but bones are starting to finish too...
And by the way, my other pets (keas, badgers and giant jack rats) can make their offspring just fine, closed in their nice earth holes. Jack rats, instead, stay disciplined and sterile (I have tons of females which used to make lots of baby rats and two or three males... which seems to have lost joy of the act).
