Why don't you want to treat your sick cat?
Hi!
My cat got fleas. He is sick now and I don't want to treat him for that He is jumping on my bed and I feel the how fleas are biting me (mainly in the head area). I'm scared.
Ah right well if that is the case I expect the cat could easily tolerate a one-time capstar oral treatment as its highly safe and will kill all the fleas in about an hour (discuss with vet). Or she could use a gentle dish soap like joy, give her a bath and comb out all the stunned fleas.
Stephen I think Malish means they can't do a flea treatment while the cat is weak from something else.
If there are enough fleas that they're jumping off to bite you, hexie is right that you need to do something. The stress/itching will only prolong any other sickness. At least get a comb and remove some of the fleas.
