I believe Angie is a really incompetent pet owner.
The fact she can’t get her cat in a cat carrier shows that this cat has never had a trip to the vets. So is presumably unvaccinated, and unchipped (which is illegal as of two weeks ago) and has never had any form of health check.
The fact that she thinks the presence of fleas is even an issue for a vet trip is also an issue. Yes, her cat should be checked by a vet since it never has been, but if your cat has fleas, buy some Advocat or Frontline. Fleas are not a vet issue. If she was any kind of decent pet owner, she would already know this.
I hope next time she tries to put the cat in the box, it claws her tiny eyes off.
