Cadette signed for Fourth Division club Southend United in a £4,000 deal in August 1985. He had an emphatic start to his career at Roots Hall, scoring four goals in a 5–1 rout of former club Orient on his full league debut for the club. He scored 56 goals in 104 appearances over the course of two seasons and celebrated promotion to the Third Division with a third-place finish at the end of the 1986–87 season. Cadette twice named in the PFA Fourth Division Team of the Year while with the Shrimpers and was also voted the club's 1985–86Player of the Year. He left the club after the season.
Cadette moved up to Second Division to sign for Sheffield United in July 1987, in a move which was settled by tribunal for £90,000. He failed to replicate his previous goalscoring form, netting just seven times in 33 appearances, before departing at the end of the 1987–88 season.
Brentford
Cadette moved back to London to sign for Third Division club Brentford in July 1988 for an £80,000 fee. Brought in by manager Steve Perryman to form a strike partnership with Gary Blissett, Cadette hit the ground running, top scoring with 17 goals in the 1988–89 season, before having his season cut short by injury in March 1989. He featured in Brentford's run to the quarter-finals of the FA Cup, which ended in a 4–0 defeat to giants Liverpool, with Cadette hitting the post with a chance which could have put the Bees 1–0 up. The arrival of Dean Holdsworthup front for the 1989–90 season and the change to route one tactics pushed Cadette out of contention. He rejected a move to a DutchEerste Divisie club in the 1990 off-season and stayed at Griffin Park on a weekly contract. He scored seven goals from 39 appearances in the 1990–91 season, which was ended after he underwent knee surgery in April 1991. Cadette was offered a new contract in the 1991 off-season, but again turned it down to remain on a weekly arrangement. He began the 1991–92 season up front alongside Holdsworth, but fell behind Blissett in the pecking order in October 1991 and departed Griffin Park in January 1992. Cadette made 123 appearances and scored 31 goals in three-and-a-half years with Brentford. Looking back in 2005, Cadette revealed that despite his differences with manager Phil Holder, he appreciated the support he received from the fans.
Out of favour at Brentford, Cadette joined Second Division strugglers Bournemouth on loan in March 1990, until the end of the 1989–90 season. He scored one goal in 8 appearances.
Cadette returned to England to sign for First Division club Millwall on loan in October 1994. He signed a permanent £130,000 deal the following month. In what turned out to be a disastrous move, Cadette made just 27 appearances and scored 6 goals in almost three years at The New Den.
Cadette rejoined Scottish League Second Division club Clydebank in late August 1997, scoring one goal in seven appearances before departing the following month.
Cadette dropped into non-league football to join Southern League Premier Division club Gloucester City during the 1997–98 season, making just three appearances.
Coaching career
After retiring as a player, Cadette became involved with the youth setup at former club Millwall. He later managed Isthmian League First Division club Tooting & Mitcham between November 2002 and May 2006. He was sacked at the end of the 2005–06 season, after defeat to Tonbridge Angels in the playoff semi-finals.
