My elderly cat recently got fleas and I treated her with frontline. She continued to itch and bite herself to the point where she had scabs along the skin on her back.
Years ago she had something similar & the vet said she had an allergy to the flea bites. I took her to the vet yesterday and they treated her with more flea drops & gave her a steroid injection for the itching.
Today she seems to be much less itchy but has suddenly gone very lethargic. Twice today I've seen her lying on the ground with her head down in front of her. She seems quite disorientated as well and her eyes are wide as if she doesn't quite know where she is.
Could this just be a side effect of the treatment yesterday? I've got another appt at the vets this aft but not sure if they're just going to charge me another £50 to tell me it's just a side effect. I did ring them to ask advice but they said the only side effects could be excessive thirst.
