When is she gonna get there just aint milk

So maybe some of you remember about 5 months ago i posted about how my kitten Mabby then 8 weeks would feed off her "brother" doofus...well suckle his nipple till it was raw and chapped.....Well mabby is about 7 months old and she still does it and doofus still lets her...Doofus has a permenetly errect nipple, and the black hair around said nipple is now brown....i swear to god its the freekiest thing...almost like mabby sucked the pigment away...Anyhoo is enough enough.....doofus doesnt seem to mind, and they are so in love with eachother...but i was just wondering.......lmao...it really is funny to see

if it is raw and chapped and you want her to stop, there is bitter apple stuff that has a sponge(you can buy a spray too) on the top so you can dab it onto cat's fur in area's you want them to leave alone, they sell it at smaller pet store chains, i dont know about big one's like petsmart and petco
it is kinda funny though!

I have tried bittewr apple...i have tried lemon juice....lime juice, all ideas from here...but they dont seem to care....isnt that bizzare....I dont know if i want to stop them....im more worried about infection but i just wondered if i should stop them...if you get my drift

yea i get ya, that is weird that none of that stuff stopped her... although stuff like that doesnt have any affect on some cats, yea i would worry too about infection and if it is raw it probably is uncomfortable for him, think about when you get chapped lips... i know it sucks for me... its probably the same on cat's skin, but i just have no clue... if that bitter stuff didnt work, then gosh, i have no idea what will... bizzare
