You're not a bad mom, Melissa. We can't know everything. This is where PT really helps us b/c we learn things from members that we might otherwise never know. As for owing the vet, they realize we're in a recession just like everyone else and as long as you're making a good faith effort to pay off the bill, I can't imagine that your vet will trouble you about it. Prayers are going up right now for your furbabies. Keep the faythe.
