Cat owner concerns

  • Biting insects like fire ants with venomous and painful bites

While caterpillar stings may not be deadly (will cause some irritation that will disappear with time, in some cases, these stings can result in severe anaphylactic allergic reactions that can be detrimental to your cat.

Too much

Finally, the possible issue that may not be serious is your cat eating too many moths or their caterpillars. Even if they may not have lethal toxins, they can still cause gastrointestinal disturbances, vomiting, or diarrhea.

May have insecticides

Insects, including moths, may have been sprayed with insecticides, which if your feline pal eats these insecticide-soaked bugs, will suffer from toxicities from the insecticides. Therefore, always try to discourage your cat from eating any insects or bugs.

Protecting your cats from moths

While they shouldn’t cause huge concern, it is always good to train your kitty not to eat bugs. Clap or softly shout stop when you see them trying to eat any bug.

Secondly, you can also use various ways to get rid of moths, including those in your house with cedar, a good option. However, never use mothballs to control these insects since it is toxic to your cats, and it may cause symptoms like:

  • Vomiting
  • Lethargy
  • Tremors
  • Seizures
  • Breathing difficulties
  • Death in serious cases

Also, please don’t use anything that isn’t pet-friendly as it will harm your cat. Talk to your vet before trying any way to get rid of these insects.
