Citrus infestation.

I think the same as my predecessor: citrus residues.

This is a learning session for me. Have not seen citrus infestations in domestic animals.

I do have a suggestion which would help differentiate plant material from parasites. I always keep a dropper bottle of Iodine near my microscope. When in doubt I challenge the material with a drop of Iodine which stains starches. I've used it on banana strings, onion slices and sesame seeds ( which look much like Mesocestoides segments). I don't know if citrus residues have enough starch to react with Iodine.

These "parasites" don't have a head, not a tail and no guys. Definitely not parasites. As mentioned above, they are more compatible with citrus fruit cells. Unable to associate with any particular cultivar.

First, I am not a citrus expert and will not try to associate the objects to any cultivar.
We have these oranges: Navel, Hamlin, Pineapple, Ambersweet and Valencia.
For grapefruit Florida grows: Ruby Red, Flame, Thompson, Marsh and Duncan.
For tangerines: Fallglo and Sunburst.
For tangelo: Minneola, Orlando, Nova, Sampson.
We also have Murcott, Tangor, Calamondin, Mandarin Osceola to name a few.
So you see, any attempt at the identification is would be fruitless.
Have a little fun time,
Florida Fan

It is little known that in Minnesota, a single species of native flora grows which is a member of the citrus family Rutaceae. Commonly called prickly ash (Zanthoxylum americanum) have small fruits not much more than a thin coating surrounding the seeds. They have no resemblance to those wonderful varieties noted by Florida Fan. They do have a citrusy oder. They are mostly known for their terrible thorns that can shed the flesh of inattentive hikers.

A note to Florida Fan. I am envious, I live to pick a fresh citrus right from the tree.
