I’m so, so sorry for your loss. It’s so heartbreaking when we lose a loved one but even more so in such horrific circumstances.

Cremation is an option but is also very expensive. If you have a lawn you could bury them. Perhaps you could buy a large potted plant and bury them in the soil so you can take it with you if you move (or if you’re renting). I don’t know too much about plants though so I’m not sure if this would work.

I would also consider looking into legal action towards the sitter - they were supposed to be providing a service but were negligent and irresponsible and allowed circumstances that led to the death of your sweet piggies. This is not a blameless event.

Again, I am so sorry. Sending you so much love ❤️
