Advice On Dad's Animal Hoarding Situation

Location: Southern Indiana

Hello, I'm (F18) and around 5 years ago my mom, sister, and I finally moved out of my dad's house. We had around 30-40 cats at a time then.

My dad still lives at his house, but through the past few years we had many cats die due to his neglect. He doesn't acknowledge that he's being neglectful, despite many people telling him that he is. He now has around 20 or so cats.

None of them are vaccinated, and when the weather warms back up they are definitely going to get fleas again.

A lot of them are neutered, none of the females are spayed, but he had some young boys left over which keep getting cats pregnant.

The kittens barely survive, and at least one of them gets sick or an infection. He open feeds the cats with 3 food bowls, and has around 4-5 litter boxes. They pee in their food bowls and all over the house. Many are malnourished or have infections in their ears or eyes.

This is what my life was like for 10+ years when my parents still lived together. Everything was dirty and destroyed by the cats.

After we moved out, more cats started to die. My dad told us if we left, all the cats were going to die, which is what's happening now. He makes it my responsibility too, constantly asking me questions on what to do for the cats and when one ends up dying he blames everyone but himself.

Recently he sent me a photo of a cat that had a prolapsed uterus. She had given birth for the second time. I told him to take her to the vet immediately but he's basically bed ridden from a recent car accident that caused him to have multiple surgeries on his foot.

He managed to get his mom (my grandma) to bring her to the vet. But she lost too much blood and had to be euthanized.

He says he loves these cats, and that they're all that he has, but lets this happen to them. I want the cats to have better homes or something, but he keeps telling me the shelter will euthanize all of them.

I would have reported him earlier, but he financially supports me, my mom, and my sister, and I get insurance through his job. If I report him, he will likely go to jail due to him having drugs in the home (mostly weed products, which are illegal in Indiana, and possibly stronger ones too.)

He also is incredibly volatile and I am worried if he were to have his cats taken he would take his own life or try to harm me or my family. In addition to this, my mom and grandma (his mom) are not supportive of my idea, as they greatly enable his abuse and my mom gets weed from him. The only ones on my side are my therapist and my girlfriend.

My main concern is getting the cats out of the house, especially 2 of the older cats. I don't want any of them to be euthanized and would like to adopt those 2 cats, but it seems unlikely due to my living situation. I don't know what to do. Is there any way I can help the cats without ruining everything else?
