Hi all i am in need of some advice, I have had cats all my life but this has me stumped. I have 2 female cats and one male cat at the moment. The females are indoor cats and the problem i have is this:- My younger cat (Gabriel) who is almost a year old keeps suckling my older cat (Frodo) who is nearly 8. This has been ongoing since we got Gabriel and i thought she would grow out of it or Frodo would tell her off but this is not the case. Now Frodo has a very enlarged nipple which when pressed feels like a swelling/lump inside and is purple and swollen on the nipple itself. Her abdominal also looks like its drooping now from the side or back when she is walking due to this. To be honest from looking at the nipple if it was me id be hitting the roof with pain but she doesnt seem to care at all. Is this due to the suckling or could it be something more serious? Frodo doesnt seem any different (normal behaviour and is eating ok etc) and i dont want to take her to the vets if its nothing i cant handle myself. I have tried to prevent Gabriel from doing this by coaxing her off and taking her away from Frodo but it isnt working. I have been reading other forums which say what Gabriel is doing is like a comfort or that she wasnt weaned enough when she was a kitten and i actually believe this to have some sort of truth behind it as she was extremely young when she was given to me (only just weaned) but its obviously affecting Frodo..... How can i effectively stop Gabriel suckling Frodo? as if it can be done for like a month or so and i keep an eye on the swelling and it goes down etc then there would be no need for the expense of a vet. Obviously the same side of the coin suggests if it is something more serious i may loose Frodo in the time it takes for me to realise this but i noticed it a few months ago and has not increased or reduced in size and Frodos behaviour has not changed in the slightest. If there is anyone else out there that has cats that have done this and they have taken them to the vets etc then what did the vet suggest to them?
