I know what you mean about always learning,i to have kept piggies for 4 to 5 years,i had a break for about 12 months due to illness,there alot i have learnt by being on this forum and researching,theres always something to make piggies lives better,they are very addictive. My daughter who is 14 helps me a great deal with cuddles,feeding etc. i have 3 at the moment but no doubt that number will grow over time,lol.
