oh I'm sorry to find this, sweetie.

uh.. it's difficult to know.. stephanie, where was the first time? in backyard? indoor? splinter's room? ..maybe a behavior aggression? but four year-old after four years together?

I'm not sure, yet. but what I think you could do is try & PM gina(gt)?

anyhow, hope this just won't happen again & I'll check back in!

good thoughts for a solution, hugggs --
