Hi, my cat just gave birth 2 days ago and has this large lump on her lower abdomen. She has given birth to 4 healthy kittens and my cat also seems healthy as well. The lump seems a bit hard. Is this a worry?

This could be a swollen mammary gland that got very inflamed, it's quite common in lactating cats, you should get it checked by your vet as she may need to take anti inflammatories if it is bothering her.
