Item 4
Changes in Registrant's Certifying Accountant
     (a) On March 14, 1997, PetHealth systems, Inc. (formerly
Triangle, Inc.)("Registrant") dismissed Schmidt + Associates, P.C.
("Schmidt") as its principal independent public accountants.
     (b) Schmidt had audited the financial statements of the
Registrant since 1981.  During the two fiscal years ended December
31, 1996, and the interim period preceding the dismissal, there
were no disagreements with Schmidt on any matter of accounting
principles or practices, financial statement disclosure or auditing
scope or procedure which if not resolved to the satisfaction of
Schmidt would have caused Schmidt to make reference to any such
matter in their reports, nor were there any other reportable
events.
     (c) Schmidt's reports on the financial statements of the
Registrant and its subsidiaries during the two fiscal years ended
December 31, 1995, did not contain an adverse opinion or a
disclaimer of opinion nor were they qualified or modified as to
uncertainty, audit scope or accounting principles except as
follows: Schmidt stated that the registrant had suffered from
recurring losses from operations and had a net capital deficiency
which raised substantial doubt about its ability to continue as a
going concern.
     (d) The decision to change the Registrant's principal
independent public accountants was approved by its Board of
Directors.
     (e) As of March 14, 1997, the Board of Directors appointed
Janet Loss, C.P.A., P.C. as the principal independent public
accountant to audit the financial statements of the Registrant as
of and for the year ending December 31, 1996.
     (f) During the two fiscal years ended December 31, 1996, and
the interim period preceding the engagement of Janet Loss, C.P.A.,
P.C. the Registrant did not consult with Janet Loss, C.P.A., P.C.
regarding either the application of accounting principles to a
specified transaction or the type of audit opinion that might be
rendered.
     (g) The Registrant has requested Schmidt & Associates to
furnish it with a letter addressed to the Securities and Exchange
Commission stating whether it agrees with the statements made in
(a), (b) and (c) above.  A copy of that letter will be filed as an
Exhibit to this Report on Form 8-K within 10 business days after
the filing of this report.
