Do you have a real legal problem? I thought you are joking.
Whatever, an animal and its name can never create legitimate interest to possess a domain that matches the right of a name IMHO. To easy. You can register it, use it - but lose it if the name holder feels hurt in his rights.
Not my opinion, rules from ICANN

a. Applicable Disputes. You are required to submit to a mandatory administrative proceeding in the event that a third party (a "complainant") asserts to the applicable Provider, in compliance with the Rules of Procedure, that
(i) your domain name is identical or confusingly similar to a trademark or service mark in which the complainant has rights; and
(ii) you have no rights or legitimate interests in respect of the domain name; and
(iii) your domain name has been registered and is being used in bad faith.
*** In the administrative proceeding, the complainant must prove that each of these three elements are present. ***
Paragraph 4(a)(iii), the following circumstances, in particular but without limitation, if found by the Panel to be present, shall be evidence of the registration and use of a domain name in bad faith:
(i) circumstances indicating that you have registered or you have acquired the domain name primarily for the purpose of selling, renting, or otherwise transferring the domain name registration to the complainant who is the owner of the trademark or service mark or to a competitor of that complainant, for valuable consideration in excess of your documented out-of-pocket costs directly related to the domain name; or
(ii) you have registered the domain name in order to prevent the owner of the trademark or service mark from reflecting the mark in a corresponding domain name, provided that you have engaged in a pattern of such conduct; or
(iii) you have registered the domain name primarily for the purpose of disrupting the business of a competitor; or
(iv) by using the domain name, you have intentionally attempted to attract, for commercial gain, Internet users to your web site or other on-line location, by creating a likelihood of confusion with the complainant's mark as to the source, sponsorship, affiliation, or endorsement of your web site or location or of a product or service on your web site or location.
