The Mad Catz R.A.T. 4+ is a good mid-level gaming mouse with a distinct gamer look and three side buttons. It feels reasonably well-built, but the plastic segments that make up the body feel cheap, and the mouse rattles when you shake it. It has an adjustable palm area that lets you change the length of the mouse, making it suitable for all hand sizes using any grip type. However, some users may find its segmented design uncomfortable. It also has LED lighting on the underside and back, but it only displays red. Performance-wise, it has a very consistent sensor, a very low lift-off distance, and a CPI you can adjust by increments of 50 within a broad range. Unfortunately, the mouse is a bit on the heavy side, and it has very high click latency for a gaming mouse.

Our Verdict

6.7 Office/Multimedia

The Mad Catz R.A.T. 4+ is adequate for office and multimedia work. It has an adjustable palm section that allows you to adjust the length of the mouse, but the plastic pieces that make up the body feel cheap, and the mouse rattles when you shake it. It's well-suited for all hand sizes and grip types. Unfortunately, it's a wired-only mouse, and its wheel lacks L/R tilt buttons and doesn't unlock for free scrolling.

Pros
  • Adjustable length; suitable for all hand sizes and grip types.
  • Good number of programmable buttons.
Cons
  • Wired-only.
  • Mouse wheel lacks L/R tilt buttons and doesn't unlock for free scrolling.
7.5 Video Games (FPS)

The Mad Catz R.A.T. 4+ scores as a good FPS gaming mouse, but it's a bit heavy and has very high click latency, especially for a wired gaming mouse. The plastic pieces that make up the body feel cheap, and the mouse rattles when you shake it. Also, its cable isn't very flexible, and its mouse feet don't glide as smoothly as most other similar mice. That said, this mouse is suitable for all hand sizes and grip types. Performance-wise, it has a very low lift-off distance and a CPI you can adjust by increments of 50 within a broad range.

Pros
  • Adjustable length; suitable for all hand sizes and grip types.
  • The CPI is adjustable by increments of 50 within a wide range.
  • High maximum polling rate and a very low minimum lift-off distance.
Cons
  • High click latency.
  • A bit heavy.
7.7 Video Games (MMO)

The Mad Catz R.A.T. 4+ is good for MMO gaming, but it doesn't have nearly as many side buttons as a dedicated MMO gaming mouse. Also, the plastic segments that make up the body feel cheap, and the mouse rattles when you shake it. That said, it has an adjustable palm section, and it's universally well-suited for all hand sizes and grip types. It also has a very consistent sensor, a very low lift-off distance, and a CPI you can adjust by increments in a fairly broad range. Unfortunately, it has a very high click latency for a gaming mouse.

Pros
  • Adjustable length; suitable for all hand sizes and grip types.
  • The CPI is adjustable by increments of 50 within a wide range.
  • High maximum polling rate and a very low minimum lift-off distance.
Cons
  • High click latency.
  • Not nearly as many side buttons as a dedicated MMO gaming mouse.
7.5 Ultra-Light Gaming

The Mad Catz R.A.T. 4+ scores as a good ultra-light gaming mouse, but it's significantly heavier than what we would consider as an ultra-lightweight mouse. It also has very high click latency, its cable isn't very flexible, and its mouse feet don't glide as smoothly as those on other similar mice. Most ultra-light gaming fans will prefer a more lightweight and responsive-feeling option.

Pros
  • Adjustable length; suitable for all hand sizes and grip types.
  • The CPI is adjustable by increments of 50 within a wide range.
  • High maximum polling rate and a very low minimum lift-off distance.
Cons
  • High click latency.
  • A bit heavy.
4.8 Travel

The Mad Catz R.A.T. 4+ is a bad travel mouse as it's bulky and probably won't fit in most laptop cases. It's also doesn't have any wireless connectivity options, which can be cumbersome when you're using it in tight spaces like trains or planes. It feels reasonably well-built, but the plastic pieces that make up the body feel cheap, and the mouse rattles when you shake it. That said, it has an adjustable palm area that lets you change the length, so it's suitable for all hand sizes and grip types.

Pros
  • Adjustable length; suitable for all hand sizes and grip types.
Cons
  • Wired-only.
  • Bulky; may not fit in most laptop cases.

You can program all buttons on the Mad Catz R.A.T. 4+ except for the left-click button, scroll up/down buttons, and the "mode" button on the top left, next to the left-click button. This mode button cycles through custom settings profiles that you can configure using the software. There's also a button behind the scroll wheel that cycles between four customizable CPI settings. The large, circular side button acts as a sniper button that lowers your CPI for more precise movements.

The "mode" button on the top of the Mad Catz R.A.T. 4+ to the left of the left-click button cycles between custom settings profiles. Due to the lack of customization software for macOS, users can't set their own profiles, so this button does nothing. Otherwise, all controls on the Mad Catz R.A.T. 4+ function by default in macOS.

Differences Between Sizes And Variants

The Mad Catz R.A.T. 4+ we tested is black and there are no other color variants. You can see the label for our unit here.

Compared To Other Mice

The Mad Catz R.A.T. 4+ is a good mid-level gaming mouse with a palm section you can adjust to change the length of the mouse. Like the rest of the Mad Catz R.A.T. lineup, this mouse has an angular design with plastic plates that form the mouse body instead of a more traditional solid plastic or honeycomb shell. It offers more buttons and customizability options than the base model Mad Catz R.A.T. 2+. However, it lacks modular finger rests, thumb scroll wheels, full RGB lighting, wireless connectivity options, and other extra features found on more premium-level entries in the series. Unfortunately, it's a bit heavy, and it has a very high click latency for a gaming mouse.
