I've just bought my first Leo (far from my first reptile mind
) and it cost me; £30 for the viv, £10 for the heat mat, £26 for the stat, furniture and decor I already had lying around, and then of course £15 for the Leo.
Look on classifieds etc, I got my Leo from a breeder and my heatmat from a private advert.
Food - 3 boxes of mealworms £6, I feed the mealworms value range oatmeal and potatoes. 3 boxes last around a month, mine's only a baby. Electricity, I honestly don't notice the difference from before I had reps, and that's 12 snakes and 3 lizards later.
With regards your table, a TV stand?
