Well, I checked with my vet, and he confirmed what I was guessing. It is absolutely adviceable to shot them earlier than later, as each yearly shot is a kind of "recall" of the previous one, so if it is done in advance it doesn't harm, but if it is done too much later it can have less interaction with the antibodies origined by the previous one. Anyway the interval admitted has a bit of elasticity. This gives me the opportunity to announce to you FML friends that Orietta gifted me with 5 babies two days ago, so I'm actually dealing with a total of 14 kits, 9 from her daughter Hexe, 28 days olds, + four adults. If someone would have told me two years ago that I was going to have 18 ferrets at home, I would have considered him crazy ! See, if you like, the last photo updates of them at my site http://www.infinito.it/utenti/fbiagioni Ciao to all and hugs to your furries. Fulvio [Posted in FML issue 3120]
