My Rats my have been posioned

Question
QUESTION: I have 3 rats, Rattypatty, a female albino rat about a year old, Grim a male is a little younger then ratty patty, and Blaze a female, who was their baby, that wasn't even a year yet. Blaze and ratty patty share a large cage and grim has a small cage but he has free run of the the top of the 2 cages and a shelf wit some books on it. Anyway, I fed them at like 7 and left to stay with my boyfriend for the night and i come home after work at 5....  Ratty Patty and Blaze were dead. Blaze was on her back with blood coming from her mouth, Ratty patty was laying beside her on her belly wit blood coming out of her mouth also, they were very stiff. Grim was on the top shelf, he was fine. What do you think happen? i spoil my rats, there is no was it was anything in my room, i clean their cages often with dish soap, i cleaned it 2 days before they died. I even wipe down the wires on the cages. I feed them food I eat that everyone in this house eats.

ANSWER: Dear Samantha

That is just horrible!!  Totally horrible!! I am so sorry you had to witness this and that the girls had to go through this.  :-(
If your sure there is nothing that the two of them could have come in contact with that was poison, they both could have been killed by the male.
Now this sounds totally unlikely, but unless we can figure out what the two females may have come in contact with, there is a change that this may have occured.
I assume that you have buried the rats by now. If not I would have suggested you keep the girls cold in the refrigerator and take them to the vets for a necropsy. This is the only way to know what occured. Could the two girls have fallen perhaps?  For them to die side by side though, and the other one, the male, is fine, thats just so odd.
Was Grim neutered? I am going to assume he was or both girls would always be having babies.
Ask yourself...has any chemicals changed lately that you use for cleaning?  Is there anything at all that they could have eaten? See, dying at the same time has me puzzled.

You said they may have been posioned, but what makes you say this?

Please let me know via a follow up

Regards

QUESTION: There is no way that Grim could have gotten to them, they are in seperate cages. I honistaly think that Blaze died 1st sence she was on her back, then Ratty Patty laied next to her. I dont belive that something in my room killed them.  Grim has his cage open 24/7, he's really fat and his cage is too small for him, so he's able to climb on the top of his cage, then to the girls's cage next door, and up onto to top shelf. I never let them around eachother. I do not want to say they were poisioned, but I dont know wat else could have happen. My parents have been wanting me to get rid of them, my dad made a big deal about how they eat all the food. I dont want to think that, that's why i asked you... what about the blood comming from their mouths? I did clean the top shelf wit some bathroom cleaner earlier that week but ive done that for ever and i allways wipe it down wit a wet cloth to be sure there is no chemicals left, i move the rats to the bed when i clean it.and if that was it then wouldnt Grim be dead for sure?

ANSWER: Oh I see I see...I thought perhaps Grim lived along with them so that is why I pointed the paw at him. I feel guilty I accused him now. :-(
The blood from the mouth could be from more than one source. It could be from internal bleeding in the stomach or else bleeding from the  brain. Again, without a necropsy there is no way to know where the blood came from. If they were indeed poisoned, internal bleeding would certainly occur.
If you have done the same thing all the time and nothing has changed and your sure everything was wiped down good, I doubt it was a chemical you used.  I suggest using natural and non toxic materials for cleaning such as vinegar and water in a spray bottle.  
Do you think they could have fallen?  Also, has anyone been sick recently and if so, from what and how was it treated?

Let me know....

QUESTION: no they didnt fall, well i guess blaze did last week but she fell onto a blanket. She wasn't hurt, she didnt fall far only like a foot or so.  that wouldnt explain ratty patty tho, that's why im so sure it was posion. It's just odd they died at the same time. yea im gonna use vinegar now just in case. i probley shouldn't have buried them, i should have taken them in, but i was so upset at the time. do you think i should take grim in to the vet??

Answer
Yes, you should take him in and explain what occured with the girls.
It could be a fluke, and they both could have died from natural causes, but that is really pushing it.

I have to ask...you mentioned that your parents didnt like that rats...you dont think....?
