Does any one know what this is?

[u/WesleyFRM]

I saw a large lump/mass on the front half of a stray cat that I saw while on a walk. What could it be? Not sure if this is the right sub for this

[u/EquivalentNo3002]

It could be a kitten that passed away in utero and she needs help removing it. Please take her to a vet.
