My cat killed my hamster. Is she aggressive towards kids or will she get sick?

Cat bites can be very nasty so I always recommend antibiotic therapy and pain management to animals (and to people) who fall victim to their feline. If you decide to hold off and take a wait & see approach, rodents often hide their illnesses until they are very sick - this is a defense mechanism as they are prey animals. They will stop eating, become highly lethargic, and may develop a high fever. As for your cat and the hamster bite, I am less concerned about this but would need to see photograph of the affected area to render an official opinion on the matter. Hope this makes sense.

I'm so sorry you lost a kitten! No, they likely won't get sick from it. Cats have been known to eat their young before (even though it's not common) and have been ok. It's gross, but your cats should be fine.

Mice are not an unusual snack for cats and rarely cause any symptoms at all other than occasionally vomiting. Monitor for any severe vomiting and report to your vet if this occurs. If mouse bait is used, there is a possibility she may be exposed to this so monitor for any other unusual signs

If your cat didn't eat it, health risks would be minimal. The main secondary issues from hunting are tapeworms (if they eat the mouse) and issues from fleas (so I would apply a good prevention like Revolution of Advantage Multi). Another consideration would be to make sure you don't have rodenticide poisons anywhere because if they caused the mouse's death and then your cat ate it (or a future mouse!) then they would also be exposed to it!

Probably. The whole mouse is technically edible for cats. A lot of hair or bones could cause an obstruction in a kitten, so I would monitor Holly for decreased appetite or vomiting. If this occurs, have her examined by a vet.

Thanks for reaching out about Smores. Cat bites and scratches can often lead to significant infections, as both carry bacteria that can contaminate wounds. Providing water through a syringe if Smores is not drinking, can provide well needed hydration until an appointment can be made with a veterinarian. A bite or scratch wound will often need to be treated with systemic antibiotics. Good luck.

There are a few diseases that a wild rabbit can carry, but fortunately they are not commonly ones that would affect people, or be easily transmitted from the cat to people. There are a few different parasites that they can get from rabbits, so it will be a good idea to have her dewormed sometime soon to prevent the worms from growing. Your vet can recommend the best dewormer to prevent the worms of concern with rabbits (roundworms and tapeworms are the more common ones). As long as Sunday is not showing any signs of illness, the chances of her transmitting a disease like tularemia (https://www.cdc.gov/tularemia/) is not likely. If she happens to appear ill (vomiting, decrease in activity, decrease in appetite, diarrhea, breathing heavily, etc.), then it would be best to keep her away from your children and have a vet evaluate her as soon as possible. It would be rare for her to have acquired a disease that she can transmit to you or your children, but you can always take some precautions just to be sure. You can keep her separate (contact is really the only concern) from the children for 7-10 days to be extra safe. If she does not have any signs of illness during this time, then it's very unlikely she will have a disease that can be transmitted. I hope that helps and all is well.
