Dc and I have owned rabbits for years.
Rescue is a good idea, because you can choose two that have already been together long term and are known to get on. They can do each other damage if they fall out!
They vary a lot temperamentally. We have had lap cuddly ones, stand offish ones, scared-of-us ones, responsive friendly ones and very independent ones. We have never had an aggressive one , but they exist. One of our current ones has severe agoraphobia, and panics madly in a big hutch, and it only settled in a tiny cramped one!
They are fine in a dark garage if it is cold, in the wild they live mostly in the dark.
they need immunising and yearly vet check ups. There are far more rabbit diseases around now than there used to be. Females also need spaying, as about half will get uterine cancer if you don't. Also, they are happier if spayed/neutered.
They shouldn't be fed rabbit food! (Ikr
!) We learnt this the hard way. Their bodies are designed to grind out the last minute percentage of nutrient from masses of very low nutrient food, and so they need hay. We do give rabbit food in very small amounts to one of ours, because she likes it, and quite frankly, she is 12, so she can have what ever she wants. The other had digestive and tooth problems, even though we were only giving her tiny amounts, so can't have any more, ever, or carrots or fruit, poor thing, but she loves dandelions, and they are still on the allowed list.
The cage needs a padlock. Foxes and rabbitnappers can open loose bolts.
They can live more than 10 years, or die unexpectedly at any time
( you also need to keep long life in mind when naming them. My 4 year old DS named one "fluffy", now is manfully sticking to it age 14, although I have offered to change the name if he would find it less embarrassing!)
They are great fun, and we love them
