First of all, they wont hate you, that is false unless you have the tazmanian devil for a cat. Cat's dont like baths, but they can tolerate them..I wouldnt recommend bathing them, without blow drying them afterwards. It's the best way to deal with the dander which is giving your friend problems with his eyes..down the road if his asthma does become a problem, without bathing you will be glad you did.

Mark my words..one day, sooner or later, you likely will have to bathe them in some way, due to back end accidents, or whatever the case..if you have them used to bathing this will go
an extremely long way when it's necessary.

I have had persians for many years..7 cats over the years, in total and as long as they are accustomed to it, there was never a problem..even better if you have someone to help you..but if not, trust me, it can
be done..I do it myself all the time..my cats presently in the past, and present have huge coats..which require a lot of care..short haired cats should be a breeze.

Start now, while they are young, and will learn to tolerate it. Pay attention to them while bathing, talk to them, praise them..it helps.

Bottom line, start young, you have good reason to, allergies.

Choose an appropriate shampoo..geared to cats. Conditioner doesnt hurt either..and rinse, rinse and rinse again.

Oh and be sure to clip front and back claws prior.
