Ohhhh, Susan!!!!!!!! I'm so so so sorry to hear what happened with your animals! I'm can't even imagine what a dreadful experience this has been for you. I'm sending loads of cyber cuddles and all the comforting pots of cinnamon tea you can stand.
I hope you can get to a place of forgiving yourself. If you'd had any idea this was going to happen, you'd have made sure it didn't. Lots of people have dogs and cats in the same house. I did! Never even occurred to me that this sort of thing might happen.
You couldn't have foreseen this, Susan. If you could have, it wouldn't have happened. Bloody hindsight. It can destroy us if we let it. Please don't go there. 💜
