Toxic farts

I am being gassed out.

I now have two dogs with toxic farts. Eeeewwww. The cats are hiding upstairs to escape the clouds of noxious gases the pair of them are emitting, and I am sorely tempted to do the same.
Added to that the fact that Lila has a major tizzy every single time Zach even looks at one of her toys. Please note that all toys belong to Lila, even those I bought for Zach. She doesn't do sharing at all.

Other than that, the pair get on fine. They have a shared love of eating, farting, and generally being in the way that will see them past their toy difficulties.
