Hello, sorry it's taken me so long to reply, but it's been a very long summer, working huge amount of hours, as well as running TEAS!
Lethal white piggies can lead a really good life and as they have never been able to see or hear, they don't miss those senses and their other senses are more heightened, so they can manage really well. In fact they tend to be much more laid back than a 'normal' piggy who finds life can be quite stressful, as a prey species.
Do you have a vet who can deal with the dental issue that is looking likely with your baby piggy? Please don't let your vet remove the remaining incisors. We have recently taken on some lethal white piggies, where the previous rescue had all the incisors removed, as they had one missing, thinking that it would mean they wouldn't need ongoing veterinary care. However, this has made it much more difficult for them to eat, as they need to pick up food with their lips and get it into their mouths far enough, that they can grab it with their cheek teeth. Also, it is looking like the removal of the incisors has damaged the roots of the first few back teeth, so all in all it has been a disaster. We are managing this, but it is needing very frequent vet trips. However, for those who have kept the incisors they were born with, they just need occasional burring of those teeth, as they sometimes get a bit long, as they don't always have an opposing tooth to wear against.
When we first had lethal white piggies, I would always keep their cage lay out the same, but then I got to thinking that must be very boring for them, so now I change things around and they soon figure it out! I always pair them with other piggies, lethal or normal, as they need company just the same as any other piggy does. I have had a lethal white neutered, who came to us with his dad, but when he reached adolescence he fell out with daddy and wouldn't pair with any other boars, so he was neutered and six weeks later he got two lady friends to love.
How is your little one doing so far. Are they feeding off mum? Do you know whether they are male or female? If they aren't feeding off mum you can always give brown bread soaked in goats milk and they will often suck that from the bread.
