A predator-prey model of a special type is considered. It is shown that the model has a phase portrait with two limit cycles enclosing a hyperbolic equilibrium each for some values of parameters. This result supplements previous results of the authors of the model.
Keywords: predator-prey model
Mots-clés : limit cycles.
