Qurbaani if one has debts

Q: I'm from Hyderabad, India and currently reside in Doha (from last March). The thing is I was in Saudi Arabia for 6 years and from December 2011 my toughest period of life started, Alhamulillah, I'm now quite fine. The thing is I was jobless, without any salary from December 2011 till 28th Feb 2013, which is more than 14 months of joblessness. During this time, I dipped into deep financial crisis and had to borrow money from nears & dears for me and my wife/son's survival. Alhamdulillah, to this day, I've repaid the debts of 4 persons out of 10. Insha Allah I hope to clear off the remaining debts too. My question now is am I eligble for Qurbaani? Can I opt for Qurbaani in A cow instead of sheep? Please advise me.
