Help!!! ?I don't want my plant to die!!

I don't know what happened but the top of my polyploid seedling is missing it still has roots and 1/2 the stem but it was only 2 weeks old...is there any way it will survive now..this wasn't bugs it was tampering by animals......is there any way to save it?it was the plant that is my siggy just a week older ..there are no leaves on it just stem and roots!!! Okay quick update if anyone is reading...so the stem appears to have healed...it hasn't wilted or anything is this a sign it has a chance?

=( im sorry man... I'm not sure anyone can answer your question better than you can though!

when the plant was damaged had it developed its first set of true leaves yet? (serrated edges)

Are you kidding?
If the plant is the one in your avatar and the top was removed there is nothing left.

probably animals dude, my cats ate the tops of some of my 1 week olds also.. had to toss the bare stem.. know it sucks.. but them the breaks of not growing in protected area

the plant was three weeks i was thinking it was 2 but it did have its first set of true leaves just came in like 5 days ago....it sucks cause it was special cause it was a polyploid...damn...i am just gonna take care of it for a couple more weeks and hope for the best and expect the worst....i still have several healthy plants that was just my special one...oh well...
