my cats i don't know what to do

[animad]

as most of you know i lost a catlast year and recently i have adopted a new one - a boy! my other cats seem to be having problems not with him but just problems, first my middle one she is smallfor age about the size of a ten week old kitten and she is four, she seemed to scratch her neck when we gave her flea treatment so we stoppedusing that kind and used pills. now she is still scratching and licking her fur in one spot which has created a circle wound which if we ignore heals if we dont she scratches what can i do to stop her? my second is my oldest cat she is only 10 years oldand seemsto keep wheezing she is slightly overweight due to her just sleeping and eating, i think it may just be a furball any ideas how to get rid of it or any ideas on what it is?
thnx animad

Your kitten might have ringworm. I suggest taking it to a vet. Sorry if i'm wrong.
