What does it mean?

i got two new piggies on monday, my first

when i stroke them sometimes they feel like theyre shivering, like vibrating

What does this mean?

It means they like what you are doing, you'll notice they do a little purr at the same time, its a good sign x

oh thank goodness!

i was worried he was uncomfortable so i put him down

I have a small dog and i know when he's scared/ cold he trembles

but thats a relief

thanks!
