Is Pro-Sense dewormer safe for my cat? Is piperazine harmful?
Piperazine is safe to give to cats, and you can give the Pro-Sense deworming treatment to Ella. It's not my favorite deworming treatment for cats, I like Panacur and Drontal, both of which you can get from your vet. Her respiratory rate is normal, but it is concerning she is acting a little weak. A heavy worm burden would cause her to lose some weight and be a little lethargic, but I wouldn't be too concerned yet she has FeLV. You would see other signs such as persistent diarrhea, anemia, lethargy, enlarged lymph nodes, and progressive weight loss among others. If you are concerned about Ella having FeLV, I would speak to your vet about running blood tests to see if she does have anemia, and possibly doing a bone marrow aspirate. I hope this helps!
