But I think this quote from a holistic DVM may answer your question: “A tapeworm could make a cat just not feel well, and when a cat doe snot feel well, their 3rd eyelid will come up, or their eyes are slightly closed. This does not happen when very healthy cats get tapeworms from fleas or mice, though.” Dr. Christina Chambreau, http://www.christinachambreau.com

What I would do is get some Echinacea & Goldenseal Liquid .

This what I have used for years on all my cats if they start showing signs of sickness. I normally give about 1/4 to 1/2 dropper per cat (10-20 drops). The dropper has 0.05ml and 1.0ml measurements lines so the dose would be 0.25ml or 0.50ml. I use the smaller dose for several days and then move up if needed.

PS- I don’t try and dose them drop by drop. I just do a decent guess and eyeball the dose and then squirt the stuff in one go. The liquid is sticky and slightly bitter but all of my cats tolerate this liquid very well, even the one with the sensitive stomach. I use it for about 5 days on, then 2 days off (to check results). If your cat’s condition worsens or shows no improvements, you need to bit the bullet and see your vet.

Hope this helps.
