We calculate the number of animals with area k living on l stairs. The total number of animals with area k is given by the generalized Fibonacci number F_p(k). Exact results for the mean length and mean height of animals with area k are also obtained and we examine their asymptotic behaviour.10 pages, 1 figure, LaTeX2e, epsf+Elsevier macro, minor correctionStatistical Mechanicstext
