Male Baldness Info

I just adopted two older Ferrets. The male is 6-7 yrs old and the female is 5 yrs old. The male ferret has a large tumor on the right side of his neck under his chin. It is an open sore and bleeds if he brushes it against anything. It doesn’t seem to hurt him, but it bothers me that it is like this. The lady I got the ferrets from said she took him to the vet and they said it is not uncommon for ferrets to get tumors like this and he is fine and that nothing could be done. The female ferret is almost completely bald. Again the lady said the vet said that it is from eating food that is not ferret food and it’s common. Yet, when I picked them up they were both eating cat food. I have changed them to ferret food and am making sure that they are sleeping in a warm, dry place so their problems will not get worse. Also, the male ferret has fleas and is starting to lose hair on his tail. The female has flea bites as well, but no hair for them to hide in. Is there anything that I can use on them for the fleas, and is there anything I can do for her baldness and his tumor? They are both very sweet ferrets and they just don’t deserve to be like this. I am wondering if any of their problems could be caused by age. I am going to make them an appointment with our vet, but I am wondering if there is anything I can do to start to help them. Thank you

complete the following crosses to predict phenotypes of the offspring.
1. cross a heterozygous tall pea plant having white, terminal flowers, homozygous green, constricted pods, homozygous yellow, homozygous round seeds and white seed coats with a short pea plant having homozygous purple, homozygous axial flowers, yellow, homozygous inflated pods, green, wrinkled seeds and homozygous colored seed coats. (10pts.)
2. cross a colorblind female, carrier of hemophilia, having homozygous A negative blood and homozygous for a full head of hair with a male having homozygous B, homozygous positve blood and homozygous for pattern baldness. (10pts)
