Soitenly. Table 7, "Heat Generated by Laboratory Animals" on Page 9-12 
of my trusty ASHRAE HOF says a 5.41 lb, normally active wabbit makes 
39.22 Btu/hr of sensible heat, according to data taken by Runkle (1964),
Kleber (1961), Besch (1973), Woods and Besch (1974), Woods et al (1974),
Bond et al [who is this al guy?] (1959) and Ott and McNully (1961.)

Impractical, I'd say. Maybe methane for cooking ("WHAT is that smell?"/
"Oh I don't know, just je ne sais quoi.") But for methane space heating,
I believe you'd need about 200 cows.

Exactly 2 x 27.21/3.41, according to Table 7, if they weigh 6.61 pounds
each, which would be true for small values of 16, or large values of 2.
