What if my cat drank water with dead maggots? Is it harmful?

Cats can be finicky eaters, and I don't imagine that Cassie would eat dried out wet food, especially if she had another source of food to eat. I wouldn't be concerned that she has eaten maggots. Best of luck.

Your kitten cannot get maggots from the food, maggots are basically the larval stage of a fly that is layed directly onto the skin, usually when an injury is present. Maggots could cause the food to get spoiled though so Junior might be suffering from a gastrointestinal infection, the main symptoms are usually vomiting and diarrhea.

If you keep finding maggots there is a relatively large infestation, You should shave the hair around the wound and wash it well with disinfectant removing all the maggots. If you cannot do that you will need to take your cat to your veterinarian for a clip, clean, disinfect, and exam. Maggots can kill your cat. Neither you nor your dog will get maggots unless you have the respective blue bottle or similar flies in your house and a wound into which the flies can lay their eggs

Maggots are usually very clearly seen when you look at the wound, it also smells extremely bad. this looks like an abscess, i don't know if she has been seen by a vet or not, if not then you need to take her to the vet ASAP, she will need antibiotic treatment.

Just wanted to add that you can use Capstar (a flea tablet that is available over the counter) to kill maggots very effectively in cats - so this is something that you could try as well. Just give the tablet by mouth, and the maggots will die within 30 minutes to an hour in most cases.

Slugs in themselves do not pose a significant problem to cat’s digestive system – insects and the like are a natural part of the feline diet. Though slugs are non-toxic, the mucous they produce may cause your cat to drool or vomit. I would be concerned, however, if there is slug deterrent used in your yard, as that is toxic to cats. Depending on the slug-deterrent used, one slug is unlikely to cause terrible results, but you can monitor Zoe for signs of agitation, excessive drooling, muscle tremors and seizures, and a racing heart rate. If you see any of those signs in her, take her to a vet right away.

I think your cat should be fine. They have to actually ingest the garlic and a clove in her water bowl should have shed enough material into the water to affect her. Of course, keep an eye out for any adverse symptoms, such as vomiting, diarrhea, lethargy, loss of appetite. If she displays any signs of illness, get her in to see your vet right away.
