In 1966, Helmut Spohr, a former football player for KSV Hessen Kassel, introduced the idea of establishing an ice hockey club.

Players started to join in the games and eventually they had enough for a team to play other regional social community groups in Hannover and Bad Nauheim.

Kassel applied and was inducted into DEL, becoming a founding member, the first time the club had reached the top division of German hockey.

[6] Using the NHL as a base model for the new league, teams became limited liability companies and took on new names often involving pseudonyms from the animal world.

Kassel head coach, Gerhard Brunner, took advantage of the new regulations and brought in an unprecedented number of European players to play for the Huskies.

The Huskies went on to lose the finals series 3–0 to Mannheim but on 16 April 1997 over 10,000 supporters filled the streets around town hall in Kassel to celebrate the team's success in becoming German runner-up for the first time.

Kassel's mayor at the time, Georg Lewandowski, led the celebrations by saying the Huskies should be proud of their achievements given just three years earlier they were playing in the 2nd Bundesliga and now they were the second best team in the country.

The solid performances under Zach led the Kassel financial supporter, Simon Kimm, to invest new money into the club.

The money secured the club and led to plans for the construction of a new Northern Hessen arena to host the Huskies and European handball team MT Melsungen.

[10] Before the start of the 2002/03 season, Kassel Huskies were rocked by news of the departure of Hans Zach to rival DEL club Kölner Haie (Cologne Sharks).

From there Kassel found it impossible to break down the Sharks’ defence and Hans once against orchestrated a famous victory over his former team for the second time in two seasons since leaving.

After eleven straight years of participation in the highest level of hockey in Germany, Kassel suffered their worst performance in the league in 2004–05.

In the eleventh hour the club secured a new major shareholder, Rainer Lippe, who took up the position of managing director with the Huskies.

[13] The wave of optimism around the new ownership of the team was short lived during 2005–06 season as the Huskies returned to familiar poor form on the ice.

The Huskies were named league premiers at the conclusion of the 2006–07 regular season, having topped the table by 13 points ahead of Grizzly Adams Wolfsburg.

During the promotion playoffs, Kassel clean swept their quarter and semi-final series’ against Eisbären Regensburg and EHC München.

[17] Kassel secured its position back in the DEL after a two-year absence on 4 July 2008 when the team agreed to two key conditions of entry.

In the league, Dominic Auger scored Kassel's first goal back in DEL, on the way to the team winning three of their opening four matches.

The financial uncertainty threatened the team's DEL licence and Rainer Lippe considered the sale of the license and his resignation as manager in order to ensure that the Kassel Huskies remained in the league.

He asked all sponsors to fill the short term €500,000 shortfall in team funds and only paid the playing staff half of what they were contractually owed.

A day later, Rossing sought and was granted an interim two week court order to lift the DEL exclusion and continue negotiations between all parties.

After further unsuccessful negotiations regarding the €2.8 million debt the DEL again denied Kassel a licence for the new season on the grounds of the team's insolvency.

In the final match, hosted in Kassel, the Huskies fought back from two goals down to win 5–2 with Manuel Klinge (twice), Alexander Heinrich, Taylor Carnevale and Mike Little all getting on the scoresheet.

The Sled Dogs won the play-offs, defeating the same opposition in the final 3–2, attaining promotion back to the top division in the process.

[43] The following are the top five all-time leaders in five different statistical categories: matches played;[48] goals;[49] assists;[50] points;[51] penalty minutes[52] A list of all head coaches, including interim, the Kassel Huskies have had since the club's inception in 1977.

[54] The most well-known Kassel Huskies fan, Liesel Burg, died 16 July 2010 at the age of 85 after attending matches and supporting the club for 30 years.

She baked cakes for players of the team every week and she was the only women to be granted regular assess to the ‘Sled Dog’ crew cabin.

Kassel went on to win the match 3–1 to please the home fans but Frankfurt coach, Bernie Johnston, was livid with the officiating in his post-match interview stating "we feel too severely punished".

While the husky image has changed a number of times on the club's logo, the mascot has been updated just once, in 2015, with a softer friendlier more 'plush' look to Hercules.

Between 1994 and 1996 the Ice Cats achieved their highest ever position in the women's German rankings, getting promoted to the second division and finishing runner-up.
