PATS, which is held twice a year, has become the UK's leading Pet Trade Show.
Yesterday was the first day of the Spring show, held at Sandown Park racecourse. The second and larger event is held at Telford in September.
Impact also organises the Aqua trade show every other year.
The impact team, led by Gordon Thomas, celebrated 10 years of exhibitions and 25 shows with the cutting of a cake.
